11 Best Freelance Software Developers [Hire in 48 Hours] | Toptal®

The Impact of the Best Software Developers

A good software developer adds significant value to an administration. But a big software developer adds more than 11 times their wage in economic respect. 1 This guide will offer you advice you can implement right away in your approaching search for the best software developers .

Prescreening

If you plan on hiring the best software developers, you will need to understand candidates on a deeper level. unfortunately, it is often impractical to grant every potential candidate an consultation, let alone a paid, week-long trial. Prescreening candidates with a simple, aim test can help you identify the ones that are worth a closer search .
Enter the tried-and-true “ FizzBuzz test ” …

The FizzBuzz Test

Question Type: Technical Skill, Expertise, and Experience

FizzBuzz Test : “ Write a program that prints the numbers from 1 to 100. But for multiples of three, print fizz alternatively of the number, and for the multiples of five, print buzz . For numbers that are multiples of both three and five, print fizzbuzz . ”

Though simpleton, this screen will screen out a amazingly boastfully number of candidates .
Depending on the function you ’ d like to fill, you can try a couple variations. For example, you can use a FizzBuzz test on each language required for the status .
In addition, it is easily to test if FizzBuzz code works. For case, in Python, you can find an on-line REPL and use it to run a candidate ’ south code, which may look something like this :

for fizzbuzz in range(1, 101):
if fizzbuzz % 3 == 0 and fizzbuzz % 5 == 0:
print("fizzbuzz")
continue
elif fizzbuzz % 3 == 0:
print("fizz")
continue
elif fizzbuzz % 5 == 0:
print("buzz")
continue
print(fizzbuzz)

If the output is correct, then they passed the test :

1
2
fizz
4
buzz
fizz
7
8
fizz
buzz
11
fizz
13
14
fizzbuzz
... etc.

now, since FizzBuzz is a pretty long-familiar screen, you may want to develop your own, like test .
Another option is to incrementally introduce new requirements .
Interviewers could besides make it less free-form by asking candidates to implement their FizzBuzz solution using your team ’ s particular software technology computer architecture. This takes the FizzBuzz test to another degree, screening out adept beginners, not just non-coders .
once you have narrowed down your applicant consortium through prescreening, you can begin assessing the remaining candidates ’ traits to find the best developers .

What Makes a High-quality Software Developer?

What makes a software developer bang-up ? The best developers will have a combination of the follow traits :

  • Technical skill, expertise, and experience
  • Leadership and initiative
  • Dedication
  • Team spirit

To help you assess these in your candidates, we have compiled a tilt of guidelines you can follow .

Pose Past Problems or Abstract Versions of Current Problems

Question Type: Technical Skill/Expertise/Experience
The best judgment of whether a campaigner ’ s skills are a adept fit to your organization is to see how the candidate approaches questions that your organization is presently working on or has encountered in the past .
Make a number of important stream or past problems your organization has encountered. Remove details from these problems that are excessively specific to your organization and/or can not be concisely explained, so that a campaigner can reasonably understand the congress of racial equality of a given issue. Pose these problems to candidates to see how they will perform on actual problems .
For example, imagine that you are developing a merchandise for IT security system managers. Your organization has spent several months creating a portal for these IT security managers to manage the intersection in their organization. You likely know the ins and outs of designing such a portal .
Ask candidates how they would go about designing such a portal, for model :

  • Which language or framework would they use?
  • How would they make the portal display in real time?
  • How would they architect the relevant databases?
  • What are some security considerations and how would they tackle these?

…while selecting the questions that are relevant to the candidate ’ second desired position. This allows a great understand of your candidate ’ s technical acumen. Because you are experienced with this problem, you will be able to assess the quality of the candidates ’ solutions and determine who is legitimately knowing and skilled .
It ’ south deserving taking the time to focus on a effect architectural trouble to see which algorithm and datum structures the candidate would find appropriate, and why. General cognition of the performance and storage characteristics of these choices is critical. even if the developer will rely on standard library implementations in most cases, knowing the “ big O ” classifications of what ’ s executing behind the scenes will mean the dispute between their work scaling—or fail .
Another authoritative aspect of a technically adept candidate is their ability and desire to mentor. Some software developers have great cognition but are unable or unwilling to mentor others. They are apt to become overload with requests and can become a single point of failure to your constitution since if they leave, it might be very difficult or impossible to pick up their exercise where they left it .

Assessing Coaching Ability

Question Type: Technical Skill/Expertise/Experience
Ask the campaigner to explain a concept to you that you already understand .
The reason you should use a concept you already understand is that you will know if the explanation is helpful and right. On the early hand, if you ask for an explanation of a concept you do not understand, you have no way of determining whether the concept is difficult, the explanation is poor, or worse, if it ’ s incorrect .

Are Their Goals Limited or Visionary?

Question Type: Leadership/Initiative
A key aspect of leadership is vision. Does the campaigner have a commission and goal they wish to accomplish by joining the character you are offering ? And is the campaigner ’ s vision broader than themselves, for example, encompassing the team or company ? For case, they might seek to solve a problem they themselves have encountered and look to make the populace a better rate. Having clear, big-picture goals makes individuals inspiring and magnetic .
vision manifests itself in concrete ways in leaders—for example, in clearing the means for the engineer team to succeed by streamlining processes and managing bureaucracy. The engineer team can then focus on producing code and delivering an great software solution .
besides, visionary leadership is often related to dedication : A software developer who exhibits the qualities of a leader will go the extra mile to overcome asperity and will boost team esprit de corps if adversity arises .

Outside-of-work Involvement

Question Type: Dedication

A bang-up software developer doesn ’ deoxythymidine monophosphate consider their job to be a job. To them, it ’ second playfulness, challenging, and matter to. And that ’ s what you want from your developer—natural commitment and date. To get a smell of that, you ’ ll want to assess whether the candidate has the desire to go above and beyond the minimal requirements of the job .
Looking at their resume, is the campaigner showing participation and interest relevant to the job outside of their professional know ? For case, does the candidate lend to open-source projects relevant to the status ? Are they actively engaged in a meetup group related to the position they are interviewing for ?
Another very significant expression to good hire is for the lease coach to take interest in the candidate ’ s goals and interests and make certain those align and expectations are met. Instances where an employee leaves soon after joining are all besides common and normally a result of not understanding the interests of the employee .
Assessment Type: Dedication
Since your goal is to hire software developers who will bring high-quality results to your exploitation team, it ’ south crucial that their aspirations, goals, and interests are reasonably met so that they can be motivated and dedicated to the project. Note this carefully, because your finish is not to hire software developers who will do the minimum until a better opportunity comes along but ones who will be passionate about the occupation .
On the same sharpen, there are well-documented cases in which hires have quit in a matter of months, with the rent director left confused. In such cases, both parties could have done a better speculate communicating their desires and listening to each other .
Assessment Type: Teamwork
Nowadays, participation in the broader on-line development residential district is standard menu for about every developer. In many cases, this may mean collaboration on open-source projects ( even just reporting issues ), or helping other developers on Stack Overflow and dedicated scheduling forums .
Before the interview stage, it ’ sulfur criterion fare to google a campaigner to find out a bit about their background. When hiring software engineers, it ’ south worth taking this a step far by exploring the public on-line communication history of a candidate :

  • How do they formulate requests for help, or answers to them?
  • When they leave comments, do they keep any criticisms constructive?
  • How do they tend to approach disagreements?

If they ’ re frequently abrasive and burn bridges in how they talk on-line, is there a good rationality to believe they won ’ metric ton do the lapp within your organization ? Assuming they ’ re even a campaigner after this exploration, any yellow flags discovered here are worth asking about in the consultation to help understand the candidate ’ sulfur perspective .
The rare developer who isn ’ t active in on-line communities may hush be a good team player. Straightforward interview questions will help you judge in this encase :

  • What are some past examples of development teamwork that they felt positive about?
  • What are some that went awry, and how did they learn and grow from them?

The anecdotes that arise from these questions will give you an opportunity to gauge how the campaigner might fit into—and affect—your team moral force .

Tips

The follow tips can greatly enhance your interviewing success .

Tip #1: Ensure Relevant Questions and Avoid Technical Minutia

screen for potency in the task you need completed, rather than width of cognition. The basic rule of hitchhike for determining if something is technical minutia or a critical technical detail is the combination of importance and frequency ; if a detail is expected to come up frequently or will have a huge shock, then it ’ s worth focusing on. Otherwise, a contingent that is improbable to ever come up—or even if it does, won ’ metric ton matter much—is best kept out of the interview rounds .
Make certain your technical questions are as relevant to the placement as possible. For example, if seeking a datum scientist ( who will chiefly work in R or Python ), it is best to not ask questions about the technical aspects of pointers and C++. even though such questions might offer an collateral judgment of a candidate ’ mho technical cognition, they are more probable to screen for the incorrect qualities. In accession, elect candidates may wonder why you are asking interview questions that have fiddling relevance to the job side and if you understand what the make entails .
It ’ s besides well to avoid program speech headscratchers and “ gotchas. ” These types of puzzles may stump flush the best of developers and have little digest on real-world exercise, specially when best practices are followed. such questions are engaging academic exercises, but they don ’ t belong in an interview as a pass/fail test, where they will surely put a barrier between your organization and great developers—even ones who can successfully answer them .
In today ’ sulfur software development space, even specialized roles can involve cognition of dozens or evening hundreds of pieces of engineering. Define a hardened of crucial elements in consultation with your stream team, but don ’ t be deterred by the fact that candidates won’t have encyclopedic knowledge of your integral development push-down storage. For model, it ’ s not authoritative that they know the appoint and routine touch of every date-handling function in the standard library of your main language. What is significant is that they ’ ra mindful such things exist and that they should default to using them whenever working with dates. Besides, every software engineering function will involve some measure of on-the-job aim and ongoing learn as the software landscape continues to evolve .
It ’ s not worth focusing on easily-looked-up syntax, either. If a compiler or linter will catch it, an interview shouldn ’ metric ton. alternatively, present the candidate a amply functional development environment and some dim-witted code with a mistake in it. then, ask them ( without a visible time limit ) to walk you through the steps they take as they debug it. Whether they need to google the doctor is much less relevant than whether they succeed .
After all, even basic operators like -> , & , and . can have wildly different meanings between languages ; developers who are expected to work with multiple languages are improbable to keep these meanings straight 100 percentage of the time, specially in the nerve-racking context of an interview. The bottom occupation is, a dim-witted hands-on debug exert will give you a much better feel of their basic abilities than a closed-book quiz .
Remember, your goal is to find great software developers. If a motion or detail can be easily looked up or has no give birth on actual software development, it ’ mho best not to use it to screen candidates .

Tip #2: Offer a Trial Period

A trial period is surely an add expense that we would all prefer not to have, but it pays itself in dividends. In this era of distant study, a trial is easier than ever using effective distant tools like Slack and Zoom .
start with the smallest tasks that require the least institutional cognition, and therefore the least bemused time for the raw hire and the pillow of the team. Assign aesthetic tweaks, minor tease fixes on low-risk, detached parts of the codebase. If the relevant home documentation is lacking, the new rent will likely find it ; if the cognition gap international relations and security network ’ t excessively big, they may even be able to help improve it .
Let new hires be character of code reviews, excessively. Their opinions in this context should highlight what they ’ ra bring to the team. But it can besides reveal areas where their practices or personality may not be the best suit for your team, and how probable it is that that can be rectified .
Having to cut losses at this luff is never an easily option, but with carefully selected tasks for a trial period, your team and organization should at least come away with some cultivate completed, plus increased self-knowledge that can be used for the next test. successful trials will besides have partially onboarded the new rent and put them on firm foot to start ramping up their contributions .

Tip #3: Get as Many Opinions as Possible

Get as many opinions from your team as possible about your hire. sometimes, it ’ s the quiet ones that have the most insightful things to say !
The argue for this is, it ’ south natural for people to relate to assorted individuals differently—and this is specially true here. For case, a nervous candidate might avoid conflicting opinions with those who will decide whether to hire them but be a fiddling more comfortable being open with their future colleagues .
Whatever the dynamics may be, collecting as many people ’ south impressions as possible will more than likely assistant to reveal nuances about the candidates ’ experiences and communication patterns. Either way, you ’ ll benefit from a more accurate photograph of your candidates, and that will help you make the best selection when hiring software engineers.

Hiring the Best Developers for Your Software Development Team

You now have a bang-up template to start with for looking for the best software developers. The most significant mind to learn from this lead is that finding great employees requires being proactive and attentive. But like all worthwhile things, the choice is worth the campaign .
