I would feel alot more comfortable with a phone call, theres something about an automated interview that is just too unnatural. I was given time limits for the questions, for example a "tell me about yourself" was 1.5 min, a "did you apply for other firms" was a 1minute and they gave me a few other generic interview questions and the last question gave me 2 minutes to add any additional comments. If i were given a phone interview I rekon I wouldve been alot less nervous and I would be able to give a more well rounded description of myself, i felt like the automated interview limited myself. but thats just me
