Technical Coding Behavioral
I was contacted on LinkedIn and went for an onsite interview. Honestly, I don't think I performed my best. After the interview, I heard nothing back, not even a rejection. Weeks passed, and my follow-up messages were ignored. I'm not sure if I was a terrible candidate or if they're just impolite. The interview was quite strange; most questions were basic programming tasks like reversing a string. The most complex question was about debugging a memory leak. It didn't feel relevant for a senior role, especially for a video streaming company, as they didn't ask anything about MPEG. I couldn't tell what they were looking for. The hiring manager seemed to have one idea, but the interviewers were on a different page. The office felt very quiet and dimly lit, like a tomb. People were there, but not much interaction. They did have a cat, though. I never interacted with or heard from HR, except for the initial contact. Overall, I wasn't impressed. It felt like they hadn't hired in a long time and were unsure how to conduct the process.

- Reverse a string.
- How could you optimize a loop, and a couple other easy puzzle questions.
