Entrevista
My overall interview impression was good with OPower. In the beginning, the process moving slow. But as soon as I got an interview date, everything started moving really fast.
On my interview day I was greeted by HR and interviewed with 7 people. Each one asked me technical questions that I felt very prepared for. The questions were fair and not tricky.
OPower is one of the few companies that sends a programming assignment first. I felt this task was very beneficial to me and the employer. I always felt that other companies like Google, Amazon and AOL waste their time with phone interviews and in person interviews. OPower instead asked a very difficult question to be programmed in a week. I felt this this assignment showed my skills well.
You have to put all you skills in good use and make sure you do a good job on the assignments.
The company is located in Arlington, VA. The company has great benefits like ping pong tables and free lunches. The most attractive perspective was that they do quarterly reviews. This is important to me because it showed they cared about employees and their goals.
I recommend doing well on the programming assignment and reading their dev blog before going to the interview.
I applied online and was contacted by one of their recruiter. After spending some time going over the ususal discussion of my past experience and responsibilities I was told that the next stage of the interview process is a coding exercise. The assignment itself is not too difficult and require knowledge of some design patterns and callback structures with proper threading,but the instructions say that the solution should look like a 'production level' solution. So after spennding 5 days including a weekend to make sure that I am using property files to pick up attributes, using log4j for proper logging and making sure sifficient application progress is logged at proper log level, using sufficient jUnit and Mocito to add unit tests with runtime mocking of my service layer, adding a design document with proper UML class diagram and more, I submit the assignment. After submitting I received the instruction from the recruiter that I would hear back in 72 hours. After nine(9) days when I still haven't heard anything back, I email the recruiter again to see if I am still being considered for further interviews I get a response saying that it was decided that my background might not be best fit for the position and I am not being considered anymore.
I would have preferred to get atleast some feedback for the 5 day long task I was given and some response as to what exactly was lacking or missing from my solution and if it wasn't my code that made them decide that I wasn't fit then perhaps a few more behavioral interviews before the coding exercise would seem more appropriate.
Hiring process is a well defined SOP. Begins with Home work assignment, telephonic interview and onsite interview.

I was unlucky enough to come across one of their "rudest" engineer , he walks into room no greetings , just tells his name, straight away starts writing to the board. He was sketchy in explaining the problem statement first, it took good 30 mins to understand want he wants.. He would then stop me in between and derail thinking process.
My advice to future hires is Not to think aloud , like you would do that in amazon, google etc.. You would loose your train of thoughts , since engineers here do not realize the fact that candidate is already in pressure and let him spit out his thinking process.

Interview process is OK. But don't expect much on the constructive feedback if you are not selected. They gave me a coding question which takes around 2 days. After completion if they like, they will call you for the next interview.
