Behavioral Technical Coding
Applied online and heard back from HR for a screening interview within a week. That went well. HR sent over the next steps details in three days. Had to sign an NDA before the second round, which was a technical interview with a senior engineer. They gave me some coding tasks that were a bit tough, and I couldn't finish them. A survey to rate the interview experience was sent out after. It was professional and organized, but I didn't get the job. Got a rejection letter on the third day after the second interview.

There was a lot of miscommunication because of the language barrier. The interviewer could not understand my solution so I had to go through an example and show her. It started off with LinkedLists. She asked me to explain any one ML project from my resume. I went to explain my internship work. She asked me some basic ML questions.
Confirmed questions5 questions
- Could you reverse a linked list?
- How would you merge a vector of sorted linked lists into a single sorted linked list?
- Can you tell me about an ML project on your resume?
