Third party recruiter reached out to me, initially really good response from both third party and BP recruiter. Interview was scheduled promptly. Interview had 3 stages: 1. Coderpad DSA Test - Code Pair - Medium Difficulty 2. Technical Interview with focus on System Design, Architecture and programming concepts - Medium Difficulty - Interesting Discussion 3. Hiring Manager Interview called WWA - 50% architectural questions, 50% preset questions that HM was reading from the doc. Recruiter had clearly mentioned that it will be more of a team fitment round focusing on just cultural fit etc. First two rounds were really good and had pretty interesting and engaging conversation with the interviewer. Recruiter provided the feedback in a very short time. In the third round, from the very start the interviewer seemed disinterested in knowing me and wanted to grill me and had already came with a decision to reject me. Despite the round being cultural and team fitment, I was grilled on architectural questions, I gave a tough fight and provided all the satisfactory answers. Afterwards, the interviewer just read some team fit and culture fit questions, I answered those questions as well. Later I figured that interviewer likely had personal bias. I wanted to get and give the feedback to the recruiter, but recruiter ghosted me and did not respond when tried to contact them. Overall, it ended up being really pathetic experience. Company leadership should look into this matter and take serious actions against such biased individuals and fix their hiring process.
