TA person called me and wanted me to directly come in for the F2F interview. I asked for an exploratory call with the HM with who I will be working for. The Engineering leader got an idea of my work, and I asked him to explain roadmap/initiatives on a high level for the upcoming 3-4 months. The person said he can't talk about them, not even on a high level. This was a big letdown. During F2F round, the Design Round included Designing Youtube, and AutoSuggest - I had studied this and gave the answer with all use cases - this question was something I had answered at previous interviews and they were right designs. The interviewer had to step out for 5 minutes during the interview as he got a call. He seemed convinced about the entire design. 5 minutes post the interview, the TA person came and said the feedback is negative. This was a shocker, as the interviewer was very much convinced about the design solution. Overall, a below-par experience. The Explo calls were not scheduled well - the TA person pings me and tells the schedule, but calls me and confirms the explo call will happen 5 minutes from now, sends the Zoom link 2 minutes before the call. Isn't this very bad candidate experience. Even the F2F round was rescheduled twice. Seems like they don't care about candidate experience. Feedback wise - no clear feedback at all. Mediocre Interview experience overall.
