I'm looking for a new job due to upcoming redundancy. I work in an industry that I have never seen a job advertised as part time. However, in my current position I have good flexible working arrangements - my hours are shifted to start early and finish early, and I work from home whenever I want (officially a couple of days a week).
I have been advised to not mention flexibility until the offer stage, at which point the company are invested in you. If I tell them early on, they are unlikely to bother interviewing, if there are other candidates that don't need flexibility. I've had a couple of first interviews. This particular one is a role that I am interested in, however, the interviewer ended the interview by saying that the job is office based. You are expected to be in the office 9-6 every day. Working from home only in exceptional circumstances on occasional days. He hinted at a second interview, and I'm waiting to hear back. I didn't comment when he made the point about lack of flexibility.
So, would it be unreasonably in this case to go for a second interview and potentially waste everyone's time as he has been clear it's onsite? Or go to the interview and if they make an offer, tell them then that I need flexibility? On the one hand, I see it as good interview practice as I've been in my current job for many years so I need to build up my confidence for interviews. I was interested in the job until he spoke about flexibility. On the other hand, I can't do 9-6 in an office 5 days, no matter how good the job offer. It just won't work around child care responsibilities.
What should I do?
