Interview Scheduling: Recruiter reached out via LinkedIn. We exchanged a couple of emails. Cleared first basic mcq phone call round. I provided my availability for phone screen. Recruiter did not respond for a couple of days and after that the recruiter said she could not “locate” my email. That was the first red flag. The recruiter did not took my seriously it seems then why reach out in the first place. Weird! Interview Overview: I wrote optimal code for all the problems. After the interview, recruiter called me and told me the feedback saying that I was not supposed to write optimal code and they were expecting simple naive solution. This is the funniest thing I’ve ever heard in my life. I have never seen interviewer asking for naive solution over optimized solution. Overall Experience: For each problem, I explained naive solution and then wrote optimal solution. The interviewer seemed very in-experienced and naive. I observed that the interviewer kept doing mute/unmute and was not communicative. I somehow feel he was not interested in understanding what I was explaining to him. At every step, I explained the interviewer why I was doing that. My goal was to write optimized and scalable solution (which I did) and not simple unoptimized solution. I made that clear in every problem while discussing my thought process. Don’t waste your time interviewing for SRE role at LinkedIn. Not worth it!
