Applied online and received an online coding challenge (HackerRank algorithm) within two days. Once completed, an internal recruiter contacted me to arrange an online paired coding test with an Akuna engineer. This coding test also used HackerRank algorithms, but I was expected to explain my thought process while solving the problems. A day later, I received an invitation for an on-site final interview. Before the on-site visit, I was asked to provide past salary information and references.

The final round consisted of three interviews. The first was with an engineer, focusing on a HackerRank system design problem. The second interview was with a team lead, covering technical experiences and a non-coding problem-solving challenge. The third interview was a casual discussion with a company lead, with no pre-set topic.

I received an email of rejection about a week after the interviews. I reached out to the recruiter for feedback, but they were reluctant to provide any.

Overall, the interview process was well-organized. My feedback is:

1. I believe there is an over-emphasis on using HackerRank. I would prefer to see more questions related to real-world production problems.
2. I do not think the interview with the company lead is a good indicator of cultural fit for a software engineer, as the concerns of a software engineer and a company lead can differ significantly.
