Worst interview ever. The people were extremely rude and arrogant, showing no respect at all for the candidates. It was one of the worst on-site experiences I've had.

The process began with a phone interview with the hiring manager, who explained the team and the job. After some delay, he arranged a technical phone interview with one of the engineers. This interview involved collaborative coding (using Collabedit) and two basic data structure CS questions.

After not receiving a response for a week, I emailed the hiring manager, and he said a recruiter would contact me regarding the next steps. Another week passed before the on-site interview was scheduled.

During the on-site, I had a series of interviews with extremely rude people. The questions were also very strange. While I understand the need for CS questions related to the field and that basic data structure knowledge is necessary, there's a line between reasonable questions and those that are old-school and irrelevant (like electrical engineering questions about signals or waves). There were also bit masking questions, which I solved, but the interviewer wanted a one-line answer that had worse time complexity than my solution.

Google interviews are tough, but at least they ask sensible questions and are polite enough to offer direction, hints, or acknowledge that false negatives can occur. The only positive aspect of this experience was likely the food.

Trees and some really old CS questions
