I received an email not a phone requesting to setup a phone interview, I responded with a time and day I was available never received a response. Did receive a call on the time and date requested. Because I never received a reply to my email wasn't sure I was going have an interview was as prepared as I should have been.

First got an automated phone interview where you were asked a series of questions about the job description and whether you were comfortable with them. Then followed by about 4-5 technical questions. After that got a video interview a couple weeks after with the interviewer describing the job and similar technical questions.
