    Timeline (~2 months):
    ----------------------------
    Applied in mid October. Phone interview was set-up two weeks later. On-site interview the week after. A lot of background check related activities for over a month. Offer given after all checks complete.

    Phone interview:
    -----------------------
    - 45 minutes, single interview
    - probability/statistics and algorithms questions
    - very friendly, casual
    - invited to on-site immediately afterwards

    On-site:

    - 1 "off the record" lunch with another team member
    - extremely nice, brilliant people
    - a lot of questions about my research (be prepared to talk details!)
    - brainteasers (algorithms, black-scholes, arbitrage-free pricing, statistics, order-of-magnitude estimations)

    Follow-up:
    --------------------
    - at the end of on-site, asked to submit via e-mail: references (4 phone contacts), code samples (~500 lines of code that you're particularly proud of), writing samples (e.g. a scientific paper)
    - a TON of background checks in the month following
    - got weekly phone-call updates to let me know status of my application and also so I could fill out more forms for the background check (I was truly amazed at the dedication and care they took in keeping me informed, especially since the process took so long!)
    - they also asked me about details from other offers I had

    Negotiation

    Told hiring manager the numbers from some other hedge fund offers I had at the time. DE Shaw countered with an offer that was superior in all aspects (salary, bonus, benefits) -- didn't feel the need to negotiate since it was the best offer I received and significantly more than industry average.

    Interview

    On-campus Hiring. I have an on-campus interview. The interviewer is a really nice guy. He just went through my resume, and ask some behavior questions. Nothing is special. Just prepare your stories and prepare for behavior questions. I believe the most important thing is whether your major matches the position you applied.
