Dropbox Senior Software Developer interview questions

The whole process was smooth and I had positive impressions on everyone I met. The only negative experience I had was with one of recruiters, who contacted me before and after the on-site (I was transferred from a different recruiter to her because the original one was on vacation) The chat two days before the on-site was short and dry, offering little help. Three business days after the on-site, I received an email from the recruiter saying that she had feedback and an update for me, and scheduled a phone call in the afternoon the same day. The email was cc-ed to all the recruiter/coordinator/sourcer who were ever involved in the process. My guess was that it was a requirement for them to reject a candidate over the phone instead of email, to show that they do care about candidates. Well, actually she couldn’t care less - the whole conversation lasted less than 30 seconds. She offered no feedback, and showed absolutely no interest in talking more. She really could have done that in an email. At least it’s easier to c&p empathetic words :-) I’m not being sour grape here. I enjoyed talking with many of the Dropbox people I met through the process, and will recommend other people to interview with them, even may try again sometime in the future myself. I just hope this one recruiter can improve on how she carries a conversation with just a little bit more enthusiasm, and make candidates feel welcomed.

Talked to a recruiter on the phone about Dropbox's products and available positions. Then an online coding interview session. The question wasn't tricky - string matching with rolling hash. The interviewer could be a bit more helpful to enable the best thinking out of the candidate, but ultimately as a candidate I should be a lot more prepared in algorithms when it comes to recognized companies in the bay area.
