I applied through a recruiter. The process took 4 weeks. I interviewed at Quantcast (San Francisco, CA) in Dec 2016
Interview
Recruiter reached out via LinkedIn to schedule a phone interview. Phone Interview was with a new employee who joined 1 month back. Later I was invited onsite and had 6 rounds. First round was Engineering Manager , who decided to go on a vacation. The next 4 rounds were pretty decent with standard startup style questions and 1 lunch interview where the dude was expressing his sadness working there for 4 long years.
I applied online. The process took 1 week. I interviewed at Quantcast (London, England)
Interview
A Code Test,
I didn't notice they wanted more structure or testing or mainly algorithms.
I think as part of the code test is always important to mention what is the key important things for the interviewers.
Perhaps the interview to interview is so different, seems like a capable person might just miss an interview because he hasn't done an interview for couple of years.
Recruiter had a call me with me first.
After that I was shared a take home assignment. Once that is cleared they have a follow up technical interview on the take home home assignment.
Got rejected after that, not sure of the reason of rejection as interview went fine.

Interview
The process was pretty standard. 1 phone call to explain the process, 1 coderpad and then onsite which had 4 rounds. Heavily inspired by Amazon SDE interview.
