Fairly straightforward. 30 minute phone screen, HR interview, Manager interview. Some interviews take a few hours. Nothing to prepare for really. The whole process takes too long if you ask me. Initially got a rejection email, then I got another interview request. Seemed a bit disorganized.

Fairly straight forward questions. I would say that you can prepare by researching typical interview questions online. Nothing too difficult, honestly - but make sure you are prepared to answer anything.
