Started at the career fair then had two phone interviews; one with the recruiter, the other with a District Manager. Was invited to the onsite interview the next week. It is two days and expenses are paid. I recommend you make an effort to build relationships with the other candidates and employees. While they are not officially reviewing your performance during meals and transition periods, your behavior will have an influence on their perception of you.

2 back-to-back 30min online interview, final round 2 days with HR presentation, Q&A panel, 2 interviews and 1 short business case, overall process well-organized and good experience, would get a call for offer/no offer within 2 weeks
