1 - Call with HR regarding career interests and position overview. 2 - Online assignment. Mostly consisting of SQL, UNIX commands/Scripting. 3 - 1 Hr Technical phone screen with hiring manager. Some programming questions, SQL concepts. 4 - Interviewed at their San Francisco office. Nice place. Onsite interview consisted of 7 rounds( depends on each individual case). Questions were a mix of Programming, SQL, Unix and other technical concepts related to the job. There were some behavioral rounds as well. 5 - Decision. Mine took around 3 weeks. As a whole, my interview experience with Opower has been very positive. The whole process was pretty streamlined and efficient. The only issue I had was the time they take to make a decision after the onsite interview. Mine took around 3 weeks. The compensation offered was good for the area(San Francisco). The benefits were pretty good though. But, it was a frustrating wait for me. Ultimately I had to reject their offer because I got a much better offer from another company within this 3 week time frame. But, I think they take their time in making a decision because they want to make sure to hire the best performing candidates.
