The interview process at CO is a 3 step process. 1. First step is a discussion with HR. 2. Second step is a coding challenge from CodeSignal 3. Third step is a panel interview with 5 interviewers regarding various topics Discussion with HR Right off the bat I didn't like the HR person I spoke to but I continued with the interview process regardless. He sounded totally disinterested in the hiring process and was just doing it as a job. I could make out he didn't care if the right candidate was being hired or in being a candidate advocate. This call has nothing much to do with your experience but just going through the second and third steps. Coding Challenge I was able to pass the coding challenge with some prep. There are 4 questions timed at 70 mins and is nothing like the preparatory challenge they provided which are 2 hard questions timed at 5 hours. The 4 questions range from easy to hard and can be completed in the allotted time. I was able to complete 3 of the 4. Panel Interview 3 of the 5 interviewers were nice and genuinely interested in what I had to say. Those 3 interviews went well and were the system design and the two behavioral interviews. The 4th interviewer who was a Sr Director didn't have much interest in the interview. He kept looking out his window and didn't pay much attention to what I had to say. This was the case study round and the weird thing is despite your programming language preference, they only have two choices - Python and Java. My first preference was JS which was not an option. My second preference was Java but the interviewer insisted I do the case study in Python because he was more comfortable with Python. Anyways, Python is actually pretty straightforward and I was able to do the round well. But the fact that he was so disinterested left doubts in my mind. The 5th interviewer was a nice person and came with a frontend coding challenge to build an app in React. I was explicitly told by the recruiter (as verified in my notes) that this was going to be an algorithmic coding challenge. Obviously, there was a mismatch and I wasn't prepared to code in React. I repeatedly told the interviewer of this mismatch and though he heard what I had to say, he never acknowledged the fact that this could be a mistake on the part of CO and the recruiter. He pressed on saying that let's talk through it and there's no need to write the code. I was able to talk through it but he clearly wasn't satisfied and kept insisting how managers at CO must know how to code. This despite me repeatedly reminding him that I had cleared the first round coding challenge. That concluded the panel interview and I emailed the recruiter thanking him for arranging the interviews and also letting him know of the mismatch regarding the coding challenge interview. Didn't hear back. Followed up a second time offering to redo the round or to do a take home challenge. Didn't hear back. After a week, I get the automated response that they weren't moving ahead with my candidacy. The recruiter completely lacked communication skills and empathy and I blame him squarely for the poor experience with the interview process and subsequent outcome.
