Between 5-10 questions. Time-constrained to 30 minutes. Interviewer's request was to make sure I was giving "brief answers", although certain questions did call for some elaboration. The call dropped multiple times which was not ideal, of course, but we got through it. Very patient and kind individual I spoke with. Besides technical errors, being told a different (lower) rate of pay afterwards via email, and feeling it was not so personable (read from script), it was a fine process and I appreciated the quick response times.
