I sent my resume to an employee for referral.

A human recruiter contacted me and told me to fill out a questionnaire about my skills and interests.

I attended an interview preparation session on Google Hangouts.

I had to schedule two 45-minute interviews and choose a programming language (C++, Python, Java).

The technical interviews were similar to competitive programming platforms like Codeforces and Topcoder.

I failed the interviews. However, if I hadn't, the next stage would have been to find a host team.
