Huawei Technologies Machine Learning Engineer interview questions

The first phone interview took 1 hour. I did well in OA, the interviewer first asked me to explain my solutions on OA, that took about 20 minutes. We talked about my projects on resume for another 20 minutes. Then I was asked a medium level Leetcode question using sliding window for 10 minutes.

Sometimes, the interview process consists of 3 steps: 1) screening interview; 2) Online coding interview (several guys from the company will appear in this step); 3) Presentation to the leaders of all research gropus at Huawei
