I will soon have an interview about a possible internship.
However there are a few things which are sub-optimal:
I do not have my exam results yet - if I sign a contract now but have failed in my exams this would be a problem
I am not familiar with the technical skills - I need to learn a lot (which in general is a good thing for an internship) but the deadline is tight and they are looking for someone who is doing it fast. An internship in part-time would be the best option for me since I have other liabilities concurrently and can't spend my whole time exclusively for the internship.
I already planned some holidays which I actually can't or do not like to postpone
So, how to address those issues in an interview the best way?
Should I ask them straight at the beginning? At the end?
Is it even appropriate to mention those things or is it better to politely decline a (potential) offer which does not suit me?
Note: It's a big company. The interview will be with the technical project lead. Not the HR department
