Yep, For example a Ryanair interview, you will be asked questions regarding ATPLs,
Like what is a swept wing, what is Mcrit, How can Mcrit be reduced,
What happens to TAS in a climb?
What does this Metar mean?
How long is this Meter Valid? etc
Just general questions about your studies, you will never know what they will ask, so you need to know your stuff.
