To my delight I was just called in for an interview for a summer position at a big research institute in the UK, as a graduating physics senior (advertised for undergrads). It's been a while since I last had a job interview and I've never had one at the professional/academic level, I would like some advice on this matter. I suppose a button shirt (and pants) is sufficiently presentable for a male? The job ad stated a "working knowledge" with a high level language like C or Fortran was desired, job is data analysis of a physical model's output and prepare it for comparison with satellite data for verification. I've done some fortran programming for a senior project (MC simulations), experienced with general numerical methods, what kind of technical questions should I expect, if any? Any UK-specific etiquette advice for interviews would be helpful too. Thanks in advance.
