Hi Anonymous,
pre-screening interview calls are usually fit-only calls, where you are judged on attitude, personality and communication. The usual questions are the same you would get in the fit part in the actual interview; the most common ones include:
- Tell me about yourself
- Why do you want to work for in our industry/company
- Tell me about a time when you failed
- What are your three top strengths and weaknesses
- Tell me about a time when your idea was criticized
- Which role do you play in a team
- Why should I hire you
Sometimes, in particular if you perform very well, you may also get a mini case (usually 10 minutes max). Given the limited amount of time and the fact that you are over the phone or on Skype, that usually is based on market sizing.
One thing many candidates neglect to do at this stage is to prepare their own questions. Relevant questions at the end are a great way to show your interest in the company and get additional points. In the first reply at the following post you can find some more information on the ideal type of questions to ask at the end of your call:
