Google SWE interview questions

Recruiter reached out to me to apply. Took 3 months for the process to complete. Had 3 telephonic in total. After first 2 telephonic rounds recruiter told me I'd need to have additional round. So, after third interview it took 3+ week to get results. 2 out of 3 Interviewers were good but one was rather difficult and challenging. Interviewers were based in USA. I prepared from leetcode, having good problem solving helps.

Got an email during summer asking me if I was interested in apply to a SWE intern position. Then I moved forward until the last round. It was an online assessment and two phone interviews. Then the hiring committee decided to reject me.
