Interview. In the UK it’s standard to have long notice periods of generally at least one month.
Interviewer: Right so we only have a couple more questions at this point. How long is your notice period at your current job?
Me: Two months.
Interviewer: Two months?! Any chance you can get that down to one month?
Me: I can always ask at the point I hand in my notice, however obviously I can’t give any guarantees as it’s clearly written in my contract. What’s the notice period here, out of interest?
Interviewer: …. two months.
