I applied through a recruiter. The process took one week.

It was followed up by:

• Intro call
• Machine coding round
• Technical discussion
• Hiring manager round
• HR round (cultural fit)

Each round is a knock-off round. Honestly, the interviewers already have a solution mindset in which they won't accept any new answer. If you match their answer and give a copy-paste view, then you are good; otherwise, you are knocked off. I explained all the solutions to him and gave him areas of improvement where we could do better, but time didn't allow me. He still said this or that was not done. That guy was seriously doing either micromanagement work, or he is too good at coding, as no one can develop 100% quality code with full expectations unless they know the problem beforehand or have developed it multiple times. I shared the feedback with the HR team.
