Round 1: The first interview was with the software manager. It was code-based, which wasn't communicated until the actual interview. Questions focused on classes, structs, and pointers.

Round 2: The take-home coding problem involved developing a buffer for a text-editing tool.

Round 3: A conversation with the Senior Technical Recruiter covered salary expectations, immigration topics, and the next steps in the interview process.

Round 4: The on-site interview included a presentation of a project I had done, followed by four rounds of interviews and a final talk with the Senior Technical Recruiter.

• The first interview discussed how I would develop the Pac-Man game.
• The second focused on finding the highest longest sum in an array, a common LeetCode problem.
• The third interview centered around retrieving data from a database, specifically the data structures and search/retrieval methods.
• The fourth interview involved Directed Acyclic Graphs (DAGs), focusing on finding the longest path or determining if a node is part of a path leading to an end node.

Overall, everyone was friendly and nice. I was quite nervous and stumbled on some questions. When I was stuck or had questions, the interviewers guided me in a non-condescending manner.

I recommend studying everything on Glassdoor and practicing on LeetCode extensively. The presentation is also very important, so if you get an on-site interview, ensure you are well-prepared, especially for answering questions. Many quick programming questions, such as those on time complexity, are available on Glassdoor.

Difference between a directed acyclic graph and a binary search tree?

What would Reference1 say is your greatest strength?

What would Reference2 say is your greatest weakness?

Find the maximum contiguous sum in this array.
