The final power day interview round was a big joke. I prepared so much just to get rejected. But I don't really feel bad at all. Half of it was not even in my hands to control. The interviewers do NOT have a skill to take an interview. They try their best in making the interviewee panic and stressed out. In my experience, 2 of 4 rounds were very bad experience. The interviewer for one of the case interviews kept bugging in my calculations. I was given a question and while I am breaking it down in my own way, trying to solve as fast as I can, they kept provoking me and tried to change my direction to the way they think. Yes, I may be wrong and I may not think the same way like them, I may not get the same/correct END RESULT, but pulling me out of my thinking, then unclearly/indirectly directing me to some approach and then saying "ok do what you were thinking" wasted my time, confused me, and I didn't even get to the 3rd question and the time was done. I was trying my best to understand the problem and solve breaking it down, but they expect me to act like I have 15 years of experience in this field? Moreover, they were NOT good listeners, clearly, I was stopped the moment I said a number while I was literally just thinking out loud and was suddenly stopped and told to "not round off". I didn't? I repeated the same number again loud again in confusion and they say i excluded the number after the decimal earlier. Like that wasn't even the result?? I was in the middle of calculation and when I respectfully said I did say it with the number after the decimal, they straightforwardly said "No (my name)! You did NOT". I felt every part of that interviewer didn't want me to score well despite me being humble and respectful. Moving to the EQ Assessment (half disappointed already), I got judged right from the beginning if I was lying or telling the truth. I didn't even finish the first sentence and I was stopped AGAIN. The question was "Tell me about a time when you helped a teammate." I started to speak "Back in my role as a XYZ I was working with the ABC team where I knew a person who needed help-" and I was stopped. They asked "What was your role, what was the person's role, why were you 2 in that team". I swear this was wrecking me so bad inside. I clearly started answering with their questions. They have the right to ask me to repeat what I said but then the person's (i helped) role, about how we know each other? My way to frame this answer in a STAR format was totally destroyed. They needed immediate deep clarifications on things I was eventually going to speak. Right at that point, I was just praying and hoping to let me finish what I wanted to share first. They kept provoking me with questions like every word I spoke, was already a lie. I understand they may have experienced candidates who lie but why was I treated like one of them from the start? I was being genuine AND NERVOUS, the least they could do is make me feel comfortable. I agree I ruined my own interview because this was nothing like how I even practiced mock. I was the one who did bad but its only me who knows what it felt like at that moment. This was way rude and unpleasant for me. They just made me see how bad I can do. Unlike Capital One's preparation videos, I didn't feel the interviewers wanted me to win. They were on the other side, trying to see how I panic. For a second, I thought the interviewers were actually assessing how I behave under pressure. I felt so nervous and tensed in the middle and by the end of the interviews with shaking sweaty hands, that I wasn't even feel nervous when I started. If there was something wrong with me, I wouldn't have done well in the 3rd and 4th interviews? But I did. Why? Because those interviewers actually assessed my performance rather than provoking me. I did well in the final rounds, I smiled, they smiled and we had a good "conversation". I actually got my hopes high because of these 2 rounds but guess they prioritize bad things that they could find in me themselves, more than a good performance and effort I was trying to put. Just a harsh reality I wanted to share for anyone who thinks this was going to be smooth if you're in the final round. As if all that performance of step 1 - coding assessment, step 2- data challenge didn't matter at all. I don't care if the interviewers experience so many candidates like me. I don't meet so many interviewers everyday? A little professionalism? Nah, thank you for showing me this attitude or whatever, I would not want to work here anyway. All the best to those who do!
