The process is composed of 3 technical interviews and an HR interview. The process was pleasant and the interviewers were nice. The questions were fair, nothing tricky or something that is not used in day to day work, they explained in detail about the work and the team.

1. Found the opening on LinkedIn and applied. 2. Tech recruiter from the company contacted me we had an initial interview going over my CV, experience and my salary expectations. Recruiter said that my expectations were within both the senior and mid-senior ranges. 3. After over a week with no more movement from the company I received an email from the lead tech recruiter asking why I had not moved forward with the process. 4. I respond saying the the initial recruiter had not taken the agreed step to schedule a new interview. 5. The initial recruiter apologises for "having lost my data in an OS upgrade" and schedules the next interview. 6. I have the interview with an engineering manager, covering past experiences, tech stack and behavioural questions. 7. I pass that round and I receive a take-home tech challenge where I had to build a server capable of taking 2M+ TCP connections every 10 seconds. 8. I complete the challenge and submit it as agreed. 9. I receive a request for follow-up interview to cover the implementation details and do a systems design whiteboard exercise (2h total), which I do and seems to go well. 10 .Time passes (2 weeks) and I receive no feedback so I ask the recruiter and he gets back to me saying that I passed all the filters and now they need to do some internal talks to make a final decision . 11. Another week goes by and I receive a rejection email literally saying that I am not a good "cultural fit". No feedback or anything besides that. Very poor and inconsiderate taking into account the amount of time I had spent on the process. 12. I sent an email asking for better feedback in order to improve and grow, and have not received a response.
