GlobalLogic Associate Analyst interview questions

A recruiter texted to pressure me into an immediate phone interview at 6:30 PM. He asked me to respond to an email to confirm I'd received it, so I did. Then he set up a video interview with a manager for 12:30 the next day, which he cancelled without explanation while I was waiting to be let into the meeting. I emailed him to ask if they'd like to reschedule, and I got no response. It really felt like a scam, but the domain in the email address matched.
