Phase2 Technology Developer interview questions

The recruiter who set up the call made it sound like it would be a standard introductory call, but instead things moved straight into a screen share with the interviewer asking me questions about multi-threading. Given I thought this interview was more of an intro call (I tell them about me, they tell me about them, etc.) I wasn't in the right headspace, plus I don't do much with actual multi-threading, but I pushed through with it as best I could. Received a rejection email from the recruiter two days later. The total time from a recruiter reaching out to me about the job and actually being scheduled was several weeks.
