Phone Interview (HR screening) around 20 minutes.

Very straightforward, and questions can be found on Glassdoor.

45-minute Skype interview with a software engineer. Questions focused on past projects. One coding exercise involved writing a function to find a hidden guess integer given a helper function. A product design question was also asked.

45-minute Skype interview with another software engineer. Questions focused on past projects. One coding exercise involved finding the k lowest elements. I did not make it past this round.

In all interviews, the interviewer was very kind and responsive. The phone screener was not a technical recruiter and could not answer questions in detail. The software engineers were very helpful, and I could see that they enjoyed talking to me. It was a great experience, and even though I was rejected, I had a positive feeling about the whole process and will definitely try again in the future.

Write a function to find a hidden guess integer, given a helper function that will check if the guess is too low, too high, or correct.

Find the k-lowest elements of an unsorted array.
