Applied online, got an email from one of the field process engineering team about a month later to set up a phone interview. It went well, so they asked me for an in-person interview 2 weeks later, which consisted of an informal lunch and then 4 30-minute interviews. Everyone was extremely nice. This was followed up a week later with a phone interview with their VP, who was also really nice.

Supposed to be a HR screening call, was told I did not need to prepare anything, but it turned out to be a full-on interview with HR, with typical interview questions. Also was asked if I understand the responsibilities of the role and what clients the company typically work with (this was supposed to be a screening call?)
