I know for definite that the holidays aren't what mine are currently and to be honest I've no idea if they pay bonuses, what the pension is or what other perks staff get there. There is very little information on their website to go off and I didn't feel it appropriate to go into that during the first interview. Do you think it would be a reasonable question for me to ask at this stage?
I think I am going to go with a 15% rise in pay and try not to go any lower than that. I'm not exactly on mega bucks anyway so it isn't a HUGE jump in pay compared to if I was on 50-60K.
From experience I'd say the fact you are at second interview stage would entitle you to ask a few more questions about the package as second interviews tend to be more time consuming and in depth it wouldn't be unreasonable to find this out beforehand to ensure you're not wasting your time of theirs. Might be the sort of thing to discuss over the phone rather than an email as these sort of questions (from experience) can often be interpreted badly.
At the same time interview experience is always useful so asking these questions at the end of the second interview definitely wouldn't be unreasonable and if the package isn't great you've not lost out on anything apart from your time
