1st round: Initial call with a manager. Felt positive. 2nd round: In-person Interview with another manager. We discussed my past experience and my opinions on SaaS platform. Felt good. 3rd round: In-person tech interview. I solved one LC Medium problem and a system design problem related to DB design. Two interviewers were supportive and the conversation flowed smoothly. We had a long, engaging discussion that ended with laughter. 4th round: In-person behavioral interview. The interviewer offered no greeting or farewell and started by requesting a detailed account of my work history from my first job onward. The interviewer maintained a poker face throughout the interview. The conversation was challenging, and the questions felt irrelevant to the position, as if he were seeking a co-founder rather than a candidate. He would pause for extended periods without reason or reaction to my answers, giving me the impression he had taken a dislike to me. The interview took an hour but felt like a-century long. At the end, he simply said, "That's all for today's interview," without making eye contact, so I left. He did share some opinions with me, but the overall experience was negative. 5th round: A brief online video conference where we discussed the feedback from the previous interviewer and my salary expectations.
