Yesterday, I went for an interview. The job advert showed the pay scale from - for example - £21000- £23000. I have over 8 years experience in the field so assumed this would be taken into consideration. Foolishly I didn't as about the pay scale at the interview (though I thought I had blown it, so really didn't think it would be an issue anyway) nor when I was offered the job over the phone. The person who offered me the job didn't discuss the salary at that time either.
I received the offer letter which gave the salary as the lowest end of the pay scale. I really believe the role and my experience is worth somewhere from the middle of the pay scale and upwards.
Is it not 'the done thing' or frowned upon to email back and try to negotiate at this point in proceedings?
