Industry standard: email from recruiter, technical screening phone call, and then an on-site interview. The technical screening was fine (same "apache log IP address" question other candidates have already written about). On-site was a mixed bag: the culture very much feels spit between Elemental's legacy and Amazon's ruthlessly standardized processes.
All of the technical sessions during the on-site interview were done in a web-based text editor, not a programmers editor. There was no referring to language docs allowed, so you'd better know the names and expected arguments of every obscure method you're hoping to use during their algorithm drills. If you have a more practical background than a formal CS background, you're not going to do well unless you've filled in CS fundamentals.
There's a lot of soft-skills questions about experiences, good and bad . Standard behavioral-based interviewing questions, pretty much taken straight from the Amazon how-to-interview manual.
Overall, their process was quick but it wasn't really an enjoyable experience. No feedback was offered when the phone call to decline came through, and I didn't ask for any as I do not think I would reapply in the future.
