I have some questions for "@Spbink": How did your interview go with the department? What sorts of things did the hiring manager or department ask you?
I interviewed with two teams, and they were very different. Each were interviewing about eight people for the position. I was applying for programming positions, so my experience may be different from what you'll get.
The first group did a Google-style interview, where they asked me some brain teasers to see how I solved them. One was how many degrees between the hour and minute hands of a clock at 3:15. Then we just talked some about my previous programming experience, and what their department did, and the usual stuff. There were probably a few "What is your biggest weakness?" typical interview questions.
The second group was a lot more intense - they were asking really technical programming questions, using jargon, etc. The interviewer seemed almost argumentative. It may have been he just wasn't good with people, or because I was the last one they interviewed and he already had a first choice from people they had interviewed before.
Anyway, if it isn't obvious, I ended up working with the first group
Also, I read in your earlier post that housing is in parts of Burbank, Glendale/Pasadena and also Cal Tech. Do you know how much the average cost for housing would cost for 3 months in that area? I am just asking because I will be traveling from Atlanta and trying to get a feel on how much apartments cost and is the housing decent in those areas. A lot of people say look on craigslist and padlooker.com but I wanted to ask someone that was familiar with that area as well.
When I was out here, I lived with a friend and my rent was about $850. But normally for a roommate it would probably cost less - I was in a fancy area of Pasadena.
Gina, our recruiter, made an email list for all incoming interns, so a lot of people found people to live with through that. Your best bet is probably going to be looking for a summer sublet in the Caltech area, or maybe up around Burbank airport. I'd expect to spend $400-$700 a month if you have a roommate, $800-$1200 if you don't. Of course, depending on your living standards, you can always find a dirt cheap place. It wouldn't be very pleasant though
Good luck with your interviews next week! Be sure to let us know how it goes!
