I've got an offer from Rocket Fuel Inc., and obviously it is a very promising company, but I've seen reviews in Glassdoor.com, and there were a lot of bad reviews about it.
Most of nice reviews seemed to be made up by HR.
If anyone is working in Rocket Fuel, please tell me what it is like to work in Rocket Fuel.
Thank you.
I don't know specifically about Glassdoor but review sites in general tend to have either fairly positive or fairly negative reviews. I think partly people with a middling view of the product, service, employer whatever don't care enough to post a review.
In general, I think all or mostly negative reviews is at least a yellow flag.
In my experience, it is difficult, generally impossible, to detect interpersonal problems, flakiness, even extremely negative working environments in a job interview. Sometimes it comes out, but most people can put on a good face for a few hours. This is really both ways; it is also hard to evaluate job candidates as well as employers in a standard job interview process.
One option is "try and buy", where you work for the potential employer on a project for a few weeks to a few months on a contract basis with the understanding that either or both of you many decide not to go further. It appears hard for an employer to hide serious problem for more than a few days. A few days, however, is probably not long enough to detect a serious mismatch.
If it is this Rocket Fuel http://rocketfuel.com/, be especially cautious of AI (or equivalent buzzwords such as "machine learning") companies. AI seems particularly prone to questionable claims, flaky people, wishful thinking and even outright fraud.
If you have not, try to find out exactly what they are hiring you to do and on what time scale. Are they expecting an AI breakthrough in 1 quarter? I have encountered extremely optimistic plans like this; it almost never works out.
