First-round was with a senior QA person and it's more of my CV walkthrough and discussed the general Testing processes and technologies. Then for the second round, they sent a Technical question that needs to be solved in any language and I was asked to solve it and send the solution on the same day and I did it. The very next day, I was selected for the next level and the HR pushed me to give B2B Interview with 4 people each for 0.5 hours (5 mins break in-between), for 2.5 hours continuously by informing me just an hour before. First-round was more of a technical round and asked questions related to my CV. The second and third round was testing process-oriented and behavioral oriented. For the fourth round, the senior person again interviewed with some basic testing processes and tools. So, on the whole, I spent more than 6 hours on the interview process and the final person told HR will be in touch. But I never heard from her after that, and they don't even bother to inform me if they hired anyone for the position. I did follow up but no response from them.
