Resume (via referral)

OA (3 weeks upon resume submission). 2 medium, 1 hard LeetCode.

Received an email from HR stating there would be four more technical rounds.

First 1:1 technical round: 10-12 questions about recent experience, fundamental internet network knowledge, and SQL. 1 easy-medium coding question.

Second 1:1 technical round: Similar focus, this time the interviewer concentrated on my knowledge and concepts from my CV: OS, message broker, and Elasticsearch. 2 easy-medium coding questions. (1 week from the 1st round)

Received a rejection email. Perhaps the coding rounds were not smooth; I took a moment to realize where I was wrong, and I was also not too good with message brokers.

If I knew some Mandarin, it could have been a huge advantage.
