The interview process consisted of two phone interviews followed by an on-site interview.

Most of the questions were acceptable, but there were a couple of really tough ones on which I probably didn't perform too well.

One of the interviewers was slightly on the rude side. He conducted the design interview, and I was unable to have a productive discussion with him due to his dismissive attitude. In the end, he stated, 'Your design will not work.'

The overall process is very good. They treat candidates well and extend offers quite quickly. I was hoping for more time to interview at other companies, but their offer came in rather swiftly.

They will definitely test your skills. It certainly won't be an easy interview.

Questions about binary trees, hash maps, and real-world systems. I can't disclose the actual questions.
