      Backend Engineer Interview

      19 Oct 2023
      Anonymous interview candidate
      No offer
      Positive experience
      Difficult interview

      Application

      I applied online. I interviewed at Coalition in Oct 2023

      Interview

      Overall had a great experience with my recruiter Dave. Dave was very communicative and willing to take the time to give me some feedback, while other companies will usually not give feedback. The technical interviews are your typical Leetcode questions. They are 1 hour long, starting with some behavioral and then following with two Leetcode questions. I would say expect easier mediums to medium as level of difficulty. I got tripped up because I thought a question was harder than it actually was and tried to prematurely optimize, but I think the O(n^3) solution was actually the one they were looking for and I didn't have enough time to type it out, so unfortunately I didn't pass the interview. Also one thing to watch out for is the interviewer might ask if there is any way to optimize your solution when you already have the optimal solution in terms of time and space complexity (at least I think so after I google the question, they don't tell you if you are right or wrong during the interview). The behavioral interviews are also very typical questions (tell me about a time ... , etc.) that you would expect to have in other companies' interviews too. The hiring manager will dig deep /ask specific questions about your past experience during that interview.

      Interview

      First interview was a short (30 minute) "talk about your previous experience". It was fine. Second interview was a technical interview with a live coding exercise and then (according to the agenda that was sent to me) some time to talk about one of the company values. The technical portion was fine. I was given a problem to solve and some tests to pass. I finished the initial problem pretty quickly and passed the tests. Then the interview added another condition to the original problem. I added some code to meet one of the new requirements and was working on the second added requirement when the interviewer decided that the second requirement was not possible to solve. So, he modified the original problem again, and again I solved it pretty quickly, passed the tests, and we briefly discussed the correctness of my solution. Then we were supposed to discuss the company value that I had been told to prepare for, but instead we talked more about my experience and did some "Tell me about a time when ..." questions. It's hard to say exactly what they are looking for with these questions, but I felt like I did a pretty good job of giving good examples. The interviewer mentioned that he hadn't been informed of what the interview agenda was supposed to be. So, I'm not sure what happened there but it seems like if the interviewer and interviewee are given conflicting information going in, that is problematic. It was a little odd also to be given a technical interview by a single developer who wasn't very senior, and who didn't have a whole lot of professional experience altogether. At the end of the interview, apropos of nothing he recommended the book "How to Crack the Coding Interview". I'm not sure if he was trying to drop a hint to me or what. I did fine on the technical portions, so I was a little confused why he felt the need to recommend the book. At any rate, even though I can't see anything that I grossly missed on this technical interview, apparently this single developer had the power to not advance me to the next round. Honestly, with the overall experience of the interview, I consider this a bullet dodged on my part.
