Software Engineering Interview Experience - San Francisco, California
Process
I applied online in mid-August and received an email from a recruiter in mid-September to complete a HackerRank challenge (about 2 hours long).
I completed the HackerRank within a week and was contacted by the recruiter to move onto a technical screen.
I completed two phone screens, interviewed in-person, and received an offer the next day.
Questions
A really interesting graph traversal question and a recursion/data structures question where I had to code up all inputs and data structures from scratch.
