Was contacted through email by HR for a phone interview and was simultaneously asked to come in for an in-person interview at the end of the phone interview.
Met with HR at the site first and she made sure I had any questions answered that I had. Then we just had a friendly conversation until the Project Manager arrived.
The manager was very casual and friendly but wanted to make sure I was able to adapt to a changing environment, as you can expect with different projects every day. He was very open to hearing what you had to say and wanted to know more about who you are!
