Clarivate Internal Communications Manager interview questions

The interview process consisted of 3 stages. I was first called by HR after I have applied for the position. Then I had two Skype interviews. I was a little surprised during my second Skype interview. The interviewers didn't turn on their camera while mine was turned on. This made me feel uncomfortable. Moreover, the 2nd interview was conducted with two people, so it was strange to try to distinguish them by voice.
