    I have been working at OpenX full-time


    I work at OpenX because I want to work with smart people. I learn something new almost every day. We have interesting problems to solve, and there are very few companies headquartered in SoCal operating at such a large scale.

    The office is nice, with free lunches three times a week and some nice little perks.

    Pasadena is great, and you can actually buy a house near the office and laugh at the people commuting on the 405 to Santa Monica. There's also this thing called a "train" 1.5 blocks away.

    The outlook for the company appears to be bright and growth has been impressive. I enjoy going to work every day, and isn't that all that matters?


    The startup seating arrangement that crams as many desks per square foot as possible can get tiresome.

    There are a few people in important positions within Engineering that simply aren't good leaders and shouldn't have the level of people responsibility that they do.

    Advice to ManagementAdvice

    Dig into Engineering leadership and evaluate everyone's people management skills.

    IPO and make the employees lots of money.

    Application Details

    I applied online. The process took a weekinterviewed at OpenX.

    Interview Details

    Applied online and was contacted by the recruiter for the telephonic interview. First guy I talked with was very nice and asked me questions related to my resume and asked me to design a class for chess. Also asked me some general DS questions. Then in the second round, I was asked to code a problem in collabedit with a link where I can finally compile and run my code. I coded it quiet well in time without much difficulty. I missed out an edge case( very rare and difficult to figure it out in interview) which I fixed when he pointed it out to me. Later I got a mail from recruiter that I am rejected for the further interviews.

    Interview Questions
    • Don't know the reason why they rejected me in the collabedit round even after writing a executable code with all the test cases cover in the first instance. The interviewer was rude and egoistic.   Answer Question
