I have applied via the official online recruiting page. 1-2 days after, HR note me to take a phone interview. The phone interview was like standard bay area interview (LT-like coding + ml questions+ deep learning questions) with one of the Lyft software engineer. While I thought I solved quite well, no feedback until now (3 days passed).

Phone interview, technical questions on general CS foundations, algorithms and data structure. Not very difficult but a very interesting question. After this step, there is another phone interview on ML topics and then on site interviewes.
