I met a recruiter at the Grace Hopper Conference in Minneapolis in October. While there I took two of their tests, the Wonderlic test and a basic, hour long logic test. Waited about a month before hearing back from them asking me to send in a code sample (they gave me three problems and I had to choose one to solve). Once that was submitted, I had to fill out a graduate questionnaire which took about an hour. Be careful to think about your answers because I was asked about my answers during the final round interviews. After I had submitted both of those I had to wait a few weeks before getting an hour long HR interview with a recruiter. It wasn't much like an interview, and more like a conversation about your beliefs, topics you're interested in, etc. At the end of the interview, the recruiter told me she'd be setting me up for a final round of interviews in San Francisco. Went to SF, had 1 group interview and 3 interviews and a STEM presentation. The group interview was the puggle problem (I think a few other people posted about it) with people interviewing for all different TW positions (not just JC). Basically, the problem is about communication and optimization. The problem asks you to make a house with the lowest cost possible. My group successfully did this and our interviewer said it was the lowest cost she'd seen. The other group with us in the room decided to make a really fun house and not pay attention to the cost requirement and I think the interviewer was disappointed in this. So make sure you remember to follow requirements (seems obvious...). The next day, the first interview was the pair programming where two programmers come in and talk to you about your code you'd sent in earlier. They didn't have much to improve so they gave me an extension problem to implement with them. Both were really nice and very patient and helped me walk through the problem. Second interview was the Values interview. I'd recommend you're updated on current events and have a few issues you're passionate or knowledgable about. Third interview was the Technical interview. Pretty basic stuff. My interviewers were both pretty young and were both in the JC program so I got to ask them a lot about their work. You also present your STEM presentation to them. You basically get an hour to make a 5 minute presentation about any topic in science, technology, engineering or medicine and present it to your technical interviewers.
