The first interview was an architecture interview, covering both the architecture I had implemented in my previous company and a discussion about Google's autocomplete, specifically its implementation using a Trie data structure. The second interview was a 3-hour coding session at their offices. I was given an old codebase from Aidoc related to scan analysis, with a focus on Object-Oriented Design and SOLID principles. The task was to refactor the Python code into any language of my choice while ensuring I understood the original Python code. The goal was to make the code more readable, well-structured, and generic. Every 30 minutes, the interviewer would check in, provide feedback, and ask me to focus on a different aspect of the code. This process continued until the three hours were up. At the end, we reviewed everything together and conducted a sort of retro feedback session on the code, discussing how I would further improve it. The interviewers were very nice, and although I didn’t pass the second interview, my overall experience with the company and their interview process was very positive.
