The interview process was very well-structured and I was guided throughout the process by the Talent Acquisition Partner.
Similar to other Tech Companies, the structure of the interview process was as follows:
1) Recruiter Screening
2) Interview w/ Hiring Manager
3) Mock Email + Call w/ Hiring Manger & Peer
4) Interview w/ Senior Executive (VP)
5) In-person Meetup w/ Local Peers & Senior Executives
The entire process took about 6 weeks, from screening to offer. However, Amplitude employees are out of office on the week of 4th July, so 5 weeks to be exact.
I would advise that interviewees research the company, its founders & backstory, industry, market opportunity, products, and customers.
