As a follow uyp to my last bklogg, I would say go with your gut instinct and parrt of manaing that emotional response is being able to move on quickly from rejection
Rejection is easy to gauge in the interview and job offer process. No news i invariably bad news. It means that other people are being ivitied to interview or offered the job, and you are on hold. These days very few people will turn down a job, or even an interiew but it does happen. So if they say they will tell you by the end of the week, phone on Friday morning and phone back if they put you on answer phone.
The onlyt thing I can suggest earlier in the internview rounds is that you phone up if you get rejection and tell them you were very interested if they had a cancellation for interbview. I havent in truth done this very often because I hate rejection and get nercvous in that type of situation, but I have been mysterioulsy called into intervbiew at short notice on occoasion.
