Hiring Software Engineers Should Round 1 Be a Behavioral Interview Coding Challenge or Take-home Assignment?

Coding Challenge Coding Live

As a computer science graduate, and having been in the software engineering space for most of my professional career where I have been through hundreds of interviews that is not an exaggeration I have seen the good, the bad, and the ugly when it comes to interviews. I have also hired engineers so I know what it feels like to be on both sides of the interviewing table. Interviewing with every company, ranging from popular social media companies to scrappy SF startups, each has an individual process, giving the candidate a unique impression.

If you have an enormous amount of applicants. This way you can easily filter for who is serious about the job. When you get them on the phone, youll already know they have some coding chops. However, please make sure that there is some thought put into the coding questions. For instance, if you are hiring front end developers, have front-end questions, not a generic software engineering test..

Can filter the amount of desire the candidate has to work for your company. Many applicants will filter themselves by not completing the project, making the recruiters job easier.

Many of us have heard the question: What would Jesus do?

Thank you, Jeff. As for the answer to your question,how about: E. None of the above.

As far as fitting in, the less proximate physical presence required, the less you need to fit in unless youre trying to create a nice little corporate bro-zone where everything is awesome and youre just so glad to be spending 14 hours/day together being passionate and disruptive together, when you could actually get the work done in 8 hours if you just left people alone to do their work and get on with their lives. (Its also spectrum-unfriendly to put so much emphasis on sociability as opposed to competence.)

With the enormous amount of software engineers who are being hired, building a successful hiring process is extremely important. If the hiring process is too long, you can lose a candidate to another company. If it is too technical, you can end up getting engineers who are strong coding wise, but struggle socially. If you have a very informal process that is focused too heavily on behavioral aspects, you could end up getting a candidate who fits into your companys culture, but is not a strong contributor.

All else being equal: who would prefer to go with company that made them jump through the most hoops?

Easy to cheat. The fortunate thing for programmers and unfortunate things for recruiters is that the world of programmers is highly collaborative. What this means is that the solutions to a lot of algorithmic problems can be found within a couple of minutes. While interview tests ask candidates not to cheat, there is no way to be sure that they do not.

Ive had good success with the Take-Home Project, especially when it reflects the actual work thats done at a given company. Its had several benefits. First, it lets the truly dedicated professional shine and put material theyre proud of. And next, as has happened repeatedly, some candidates have a moment of honesty and decide that line of work is not for them. (Fantastic! You are free to find the employer whos right for you, and we will find the candidate whos right for us.)

A recruiter talks to the candidate on the phone screening for culture fit, communication skills, and evidence of technical competence.

Some job openings receive hundreds of applicants, so you need to filter through the candidates to find the strong ones without spending too much time. Each phase of the hiring process needs to be fine-tuned in order to efficiently find the best candidate for your company.

Jeff great analysis of the possible first round interviews for developers. I would, however, caution people interested in the Coding or Take Home Project approaches, as they would be considered tests by the EEOC. Companies need to make sure the tests, especially the timed portion, are validated in that dont create adverse impact on any specific group of candidates. Thus, having a hiring manager or anyone else simply create a coding test could create an issue for a company should a candidate challenge the selection process.

Takes time and resources to create and review the exercise. When a take-home exercise is created, that means that someone in the company has to decide on the appropriate take-home assignment. However, the big time component that comes in when the candidate finishes the assignment. Once the candidate finishes, several employees need to look over the code and evaluate whether or not the candidate passes. It takes a good amount of effort to get several programmers to stop what they are doing and evaluate, so you can expect a some lag in time before the team gets back to you.

If the hiring manager highly values communication and personableness. If this is the case, a phone call can be appropriate. However, a hiring manager and their team should weigh in the most on whether a candidate is a good fit for the team.

As mentioned earlier, these tests are very heavy on algorithms. Since people who have not graduated with a major in computer science are a lot less likely to know algorithms, a lot of candidates who are self taught or have taken boot camps will struggle on these problems. It does not mean that they are poor programmers; it just means that these questions are not common in the world of programming. By having this phase you can easily miss a large pool of qualified candidates.

Does not simulate working coding environments. Usually coding problems are algorithms and data structures, both of which are really used on the job unless the role is in a field such as artificial intelligence. Plus, its timed. I have never once had to code something under a deadline for 30 minutes. Maybe 30 hours, but never 30 minutes.

Hard Ask for First-Round Interview. Normally, the interviewer and the candidate gradually invest more in one another with each subsequent round of interviews. When a company asks a candidate to do a take-home project, they are demanding a large investment from the candidate. The candidate is much less likely to complete it because they havent yet received an equal investment from the company.

Then, it should be followed by either a couple of hours or so of sequential interviews or ideally a 60-90 min panel interview with 3-5 folks.

Can eliminate extremely strong programmers. Keep in mind that a software engineers job is mostly solitary, while a recruiters job is to communicate with people everyday. A software engineer with more introverted characteristics tends to find phone calls more uncomfortable than a recruiter, resulting in a less than perfect impression on the recruiter. There are manyarticlestouching on these points, that show that engineers preferred to be emailed for communication.

Very time consuming on the recruiters part

seen the resume. I cannot tell you how many times Ive seen a call go great with a recruiter, but then the recruiter has to reject the candidate because the hiring manager didnt think the candidate was a good fit after looking at his resume. Not only is this rough for the candidate, but it also wastes the recruiters time. It can easily be avoided if the manager first looks at the resume to make sure the candidate seems suitable on paper. (However, this does not always apply, such as at companies like Google, where the manager picks the candidate out of a pool of candidates who have passed all of the technical tests.)

Hopefully seeing the pros and cons to the different screening approaches can help you with your hiring process. Some of the biggest mistakes I see are different companies picking the wrong first round. Maybe its a really small unknown startup and they require a candidate to do a large coding assignment when the candidate has not been sold on the company yet, or a recruiter who has a copious amount of potential candidates screens everyone on the phone, leaving more qualified candidates to competing companies. With a bit more tweaking to the first part of the interview process, you could see an increase in the quality of the candidates who make it onsite.

For this article, I would like to focus on the first-round interview because I believe that is where most companies make the biggest mistakes. I will dive into the pros and cons of the most popular first-round strategies and provide solutions to optimize your hiring process. If you are a recruiter with a non-technical background, you will find this article very helpful in breaking down what a software engineer really experiences during an interview process. If you do have a technical background, then there might be a couple of nuggets of wisdom for you to try out at your company.

Take as long as you want, but not really. Often, recruiters will ask software engineers to complete the project in about X hours. The issue here is that the more time that the coder spends on the project, the greater the chances are of them moving onto the next round. This can really put a candidate in for a spin, especially if the project is difficult which they usually are. The consensus among software engineers is that X is usually the least amount of time it will take, and if you really want the job then you are probably going to need to put in a few more hours. This increases the likelihood that the candidate will not finish the project, especially if they are hot on the job market and another employee has a shorter first-round process.

Can eliminate very strong programmers.

The Demand for Degrees Is Screening Out Too Many Candidates

Candidates are given a take home project where they need to code according to the specifications decided on by the hiring manager. These can range from two hours to however long it takes the candidate to finish, which could be up to 12 hours.

In my experience, the first step step is the 30-45 min. technical phone interview. oft
