The process took 4 weeks. I interviewed at OpenX (New York, NY) in Jan 2016
Interview
Worst HR employees. Do not respond to your calls and will not refund the expenses until asked for, multiple times. Getting the feedback on the interview also is tough.
Interview is concentrated mostly on SQL no matter what job you apply for. Even for SET, they ask questions similar to SE. Even a rookie will interview you, although he cannot explain you the question correctly.
I applied online. The process took 5 days. I interviewed at OpenX (Menlo Park, CA) in Jul 2016
Interview
While I was waiting for the interview at OpenX I got an offer from other company. I told the hiring manager about that and they were able to speed things up and set up an interview in two days. That was very amazing! The interview went very good and the people in their Menlo Park office were super friendly. Overal that was very positive experience.
Interview questions [1]
Question 1
The most unexpected question was "How do you sort a dictionary in Python". The rest of the questions were pretty much expected (Python, Selenium, general questions about how would I test some function).
