The recruiter who emailed me was very nice and helpful. After the technical interview, he called me to discuss how it went. Unfortunately, I did not make it through the process. The recruiter does send you a book with things to know for your interview (Data Structures and Algorithms, etc.). The technical interview over the phone was a great experience. He asked me to write code for a Teoplitz matrix. It took me around 30 minutes to write the code, and I discussed each scenario with him. The interviewer was very helpful and gave clues on the areas where I was lacking.

When I was done, I got a chance to ask him a few questions. I asked him a technical question about airport runway flight requests landing every 15 minutes: how would you deal with it? He laughed and said he couldn't answer that question, joking that if his answer was wrong, I could tell the world. I clarified that I was just asking in general. He then asked me to rephrase the question, which I did. Finally, he answered that he would choose a HashMap.

Then I asked him one more question about his work and process. He explained all the processes and the areas he likes.

Overall, for me, it was a pretty positive experience.

Sorry, I cannot share the interview questions because they requested not to. However, I did provide some guidance on what to prepare for.
