Interviewing at FlightAware: A Guide to Joining Our Team

Interviewing at FlightAware: A Guide to Joining Our Team

Jonathan Cone is the Director of Engineering over Data and Software Services.

Some of the most important decisions we make at FlightAware are deciding who will become part of our company, team, and culture. Our company was founded by aviation geeks and big data nerds, which organically brings in people from diverse backgrounds who have a passion for aviation, software, and the services we provide. FlightAware’s success has been driven by its employees and their commitment to the quality, reliability, and innovation of its products. We strive to provide an interview experience that will identify talented candidates and sell them on the benefits of working here. It’s a continuous process to fine-tune and improve the hiring process, and we have a team of people dedicated to that endeavor. In this post, I’ll introduce the overall interview process with an emphasis on the technical interview.

The Interview Process

Candidates will submit their application (with resume) to the open job posting. Once a resume is received, we start tracking the candidate’s progress and pass their information onto that group’s hiring manager if they meet the position qualifications. The hiring manager reviews the resume to gauge interest and applicability of skills for the role in question. They may also refer the candidate to another team if the skillset doesn’t match that team’s needs. Following the resume review, the hiring manager will decide if we should initiate the interview process.

Most engineering positions at FlightAware will include the following steps. Some positions, such as Software Engineering Interns, Site Reliability Engineers, Mobile Engineers, or Data Engineers may have slightly different interview processes.

Exploratory Talent Acquisition Interview

The first step in the interview process is a non-technical exploratory interview conducted by a recruiter. The interview is typically 15 - 20 minutes, and the candidate will be asked about their background and experience. This is our first opportunity to gauge culture fit, genuine interest in the role, and to rule out any non-technical disqualifiers. Candidates who have spent some time researching the company and the role they have applied for typically do well here.

Technical Interview

Once past the initial recruiter interview, we schedule the technical interview with the candidate, which typically takes up to 90 minutes. We utilize CoderPad to facilitate this exercise as we’ve found it to be reliable, configurable, and it supports a wide variety of languages. The questions we ask during this interview are selected and curated by a group of engineers at FlightAware. We spend a non-trivial amount of time reviewing the process and the questions, proposing new and refining existing questions to ensure that we can identify the strongest candidates. There is a mix of small algorithmic and real-world problems; the candidate is also asked to solve a programming problem similar to something we might deal with at FlightAware using a programming language of their choice. We expect that the candidate’s code will compile and produce a correct result.

Our intent is not to trip anyone up by providing trick questions or problems that only the most nimble and well-versed in their language's nuances can solve. We want candidates to demonstrate how they approach solving problems, reason through questions, weigh the benefits and drawbacks of possible solutions, and verify the correctness of their response.

Again, while we expect that a candidate will produce quality code that solves the problem, a broader focus is on how the candidate approaches the problem. It behooves a candidate to talk through their solution, approach, and articulate any issues they are struggling with so that we can better make that determination. In the absence of that insight, we might pass on a candidate who just made a simple mistake but never expressed their thought process, leading us to believe they were weaker than they may really be as a developer. Depending on the candidate’s experience and position for which they are applying, there may be some follow-up questions to further probe their breadth of experience and knowledge. This technical interview serves as a go/no-go decision point for the candidate. If the candidate performs well here, they will continue with the process, and if they fall short, we will provide a written communication to share a status update.

System Design Interview

The system design interview is a discussion-based interview typically lasting 60 minutes that will be included as part of the interview process for certain positions (including most senior individual contributor roles and leadership roles). During this interview, there is no coding required nor expected, but you may need to draw out diagrams or define database schemas. This interview is usually scheduled as part of the virtual “on-site” interview described in the next section but may also be scheduled separately prior to the final non-technical interviews.

At the beginning of the interview, you will be provided a vague or ambiguous problem and asked to design a FlightAware-style system. We are evaluating how you approach defining requirements, estimating resources, and designing the components, scaling and reliability of the system. As with the previous interviews, we are examining your thought process and interested in the questions you ask to develop this system.

Non-Technical Interviews

The final step of the interview process is a virtual "on-site" interview. The interview schedule consists of meeting with managers, peers, and leadership at FlightAware as we continue to evaluate cultural fit, behavioral characteristics, and overall interest in FlightAware. The interviews’ ordering may vary, but generally the first meeting will be with the hiring manager (and potentially team manager). This interview typically focuses on behavioral questions and assesses the candidate's motivation and interest in the position and company. Here you can expect questions about successes and failures in past employment, exposure to agile development practices, and experiences working in a team environment. There may be some high-level technical questions during this stage to further suss out a candidate’s level of experience with some technology.

The candidate will generally next meet with one or two peer members from the development team. The peer interviewers will show the candidate some of the projects they are working on and products they are responsible for. The idea is to show a candidate, as much as possible, what it’s like to actually work at FlightAware. This is a good opportunity for a candidate to engage and ask questions about our development process to better understand the role and what the day-to-day work looks like. At this point, we’re both trying to sell the candidate on the role and continuing to evaluate interest and exposure to development practices. There should be many opportunities for a candidate to talk about past work and how it is applicable or not to something being undertaken at FlightAware.

Some interview processes will also include a meeting with FlightAware leadership; historically this has consisted of a meeting with either an Engineering Director or the VP of Engineering. They most likely have communicated with those involved in the interview earlier to gauge performance and will be striving to make the last sales pitch to quality candidates and the final evaluation stage. These interviews are typically about 30 - 45 minutes each. The interviews typically pose some additional behavioral questions and high-level discussion about what environments in past positions have worked well for the candidate versus those that have not. This also serves as an opportunity for a candidate to ask questions and get to know the company from a broad perspective from those responsible for the larger direction of engineering at FlightAware.

At that point, the interview is completed, and the interview team will meet to discuss the candidate’s performance and hopefully decide to make an offer!

General Timeline

Candidates are usually notified within a few days of completing their technical interview if they are proceeding to the next step in the process. The actual scheduling of each interview can vary depending upon the candidate’s schedule as well as our engineers’ schedules. The timeframe for completing the entire process can vary and the recruiter will be in contact throughout the process to keep you informed and discuss upcoming steps.

The Best Candidates

Here is a list of common traits among the candidates who have done well and been extended offers.

Be Prepared

You might think this to be an obvious task that everyone undertakes before attending an interview, but we find it to not always be the case. Even those who prepare diligently for the interview's technical portions may not have spent time understanding what the company does or what the role may entail. This is frequently exposed in the questions, or lack of questions, asked by a candidate. Spending some time exploring the website and the engineering blog before attending the interview will ensure that you have at least a high-level grasp of what FlightAware is and what we do, which hopefully leads to some interesting questions about how we manage flight tracking.

For the technical interview, there are a myriad of resources available online to help job applicants prepare for technical interviews. Spending some time on those sites is likely to increase the odds that you perform well. The questions asked during interviews may seem artificial because they are unlikely to have a 1:1 relationship with the work you do on a daily basis or in school. Our questions are limited in scope and designed to give us insights into your thought process. We could give take-home problems with larger scope, but that would not address this key interview requirement. So, spending a little time familiarizing yourself with the types of questions asked in interviews is likely to put your mind more at ease and help you feel comfortable during this high-stress period, so you perform at your best.

Finally, candidates who have spent time thinking about the types of behavioral questions that arise in interviews are, not surprisingly, better prepared to answer those questions. It can be challenging when in the heat of the moment to come up with examples of times you failed or disagreed with your boss that showcase your ability to work through a difficult environment or relationship. That’s not the sort of thing you want to wing because you may find on reflection that your response didn’t cast you in a favorable light (e.g., I just bashed my former boss in front of my new prospective boss. We don’t know you or your former boss well enough to establish who was in the right or wrong, so it’s unlikely that is going to score you any points). The task of preparing for an interview is critical and requires the same dedication you bring to your work as a developer. Those interviewing you have not known you for years, so while preparing can feel like a job unto itself, failure to do so will be perceived as a lack of seriousness on your part.

Deliver Effective Communication

The best engineers at FlightAware are also excellent communicators. Candidates that demonstrate this ability are more likely to succeed at the company. The types of problems we are solving require the collaboration of multiple individuals and teams. For those efforts to succeed, all individuals involved need to be able to effectively communicate with one another. Therefore, as a candidate, we need to see that you possess that ability as well. Ensure that your responses to questions are reasoned and concise, addressing the full topic without becoming a filibuster. Convey your past contributions to significant projects espousing your technical understanding of the problem and its solution.

Show Enthusiasm

Some are aviation enthusiasts, while some are just passionate about software. During the interview, let the enthusiasm you possess for software engineering and our industry shine through.
