ZoomInfo interview questions

I applied online and got a call from recruiter in 2 days. He was a very pleasant guy to talk to but never had the sense to book a time via email to talk before calling. And this happened on multiple occasions where once I was in a product demo meeting. He scheduled a 45 minute technical screening interview with a manager and architect where they talked for 15 minutes about what they do and what their mission is which was very good. The next 30 minutes was a very programming question for which I had a solution ready in 5 minutes with O(n) time complexity. The manager didn't asked me to optimize it and also gave me a hint about what solution he was expecting/had in mind. When I said his solution also solves the question in O(n), he probably didn't like it. Never heard back from the recruiter even after investing 2 hours of my time. Bottom line, if the solution isn't what they expect it's not correct.

Smooth and quick interview process with constantly in loop with the HR. Good team with detailed introduction and working of the company. Polite and friendly technical recruiters. The process was hassle free.
