I applied through university. The process took 1 week. I interviewed at Stripe in Oct 2018
Interview
1 hour phone interview where they can see you and your computer and you code the solution to a HackerRank style problem and essentially do virtual "whiteboarding". You will be observed by a current engineer and there is also an entry-level engineer observing you. Onsite interview are only 2 interviews long (plus casual lunch interview) for interns.
Interview questions [1]
Question 1
Read in a list of dictionaries and return the dictionary with the largest instance of a key given. Also with additional constraints and edge cases provided.
There was a recruiter call where they told me what to expect for the next couple rounds. I had a call with the hiring manager and technicals with 2 other engineers.
I applied and got an interview offer in about 2 weeks. I interviewed with someone from the US even though i applied for Bucharest. A bit of introduction and HR style questions in the beggining, followed by 2 problems.
The first step is a HackerRank challenge, typically 60 minutes long, consisting of one question broken into 3 parts/sub-tasks. The question is implementation-heavy rather than a typical dynamic programming or graph puzzle.
