      Interview

      It went for about 4-5 rounds. We talked about the role related background knowledge and some simple to medium level's algorithm problems. And another round for BQ. It's more focus on your ability to work, not just the ability to solve algorithm problem.

      Application

      The process took 2 weeks. I interviewed at F5

      Interview

      The overall impression is quite disappointing. The recruiter didn't even took the time after i went through to 3 interviews to communicate the results or feedback (negative I presume) after the technical interview. Management and techinical people seems to live in different worlds and seperate from any shared information. Did 1st interview with management which was ok, i had still some question, like who is the team, which project i will work on. I thought the technical interview would give me clarity, but Principal engineer i spoke, didn't know either which team/project I should work on. The principal engineer asked me to do coding session(there was on preparation link or video), which was not really clear announced in mails, from a Principal/Senior person, I would expect more a system design and high-level interview, but it was the "usual" college coding games interview which most of time , Senior people have difficulty to answer because nobody use them in real life and junior people excells Disappointing from the technical interview to the recruiter, I diddn't felt my experience was valued. Sad that is always the tipical way of filtering people. I would not reccomend The manager I spoke with allthough was kind and with experience
