First, they sent an online assessment. It contained one medium question and one hard question from the Leetcode DoorDash section. I passed all test cases for the first one, and I could not pass 4 tests out of 13 for the second one. I passed this phase and moved to onsite. In the onsite, there were two coding questions and one behavioral. The first interviewer asked a hard question from DoorDash Leetcode problems and the second interviewer started with an easy problem and in the follow-up, she asked two hard problems from DoorDash Leetcode section. I have done all DoorDash problems on Leetcode, and I solved all of them correctly. I also did well on the behavioral interview. But two days later, they said they decided not to move forward with my case. It was a total waste of time.
