Summary : After passing 4 rounds of technical interview, CTO said to me on call "We don't hire people from one of your past companies". Lol. Rejected. Read in detail below: 1 - Initial HR call 2 - First technical round it included: a - SOLID and Design Patterns b - Screen sharing coding session, no language no compile, just process and clean code. And a DB query and logs to look and discuss possible issue. c - Microservices and when to chose & some more questions 3 - Second Technical interview, System design on draw.io how uber/careem finds car close to you. Then a separate detailed discussion on planning a monolithic to microservice. What can happen wrong. How to tackle it. Migrating related questions. 4 - Another technical round with principle engineer, again discussed microservices. How you measure performance. What techniques to do monitoring. Code quality questions. How handle transactions in microservices. How will you scale an app and why choose the stack? 5 - CTO interview, again asked technical questions about microservices, when to choose monolithic, how you measure performance. If there is crash how will you respond? How will you observe and monitor your code? Asked about my past experiences and why did i choose specific tech stack for one of the case? On call with CTO, he said you come from a specific company and we usually dont hire people from that company:) I said, I have already cleared all 4 rounds of interviews, so i think I have what it takes to be here. So, after CTO interview, i got rejection. What a waste of time. I can not believe a CTO asking technical questions that have already been asked multiple times during previous rounds. And then finally rejecting and saying to me on call that i don't hire people from this company. I find this a very low evaluation point.
