OK, so you're an experienced hire who is happy with his current job but is feeling underpaid. If it were't for the pay, you'd certainly stay put (but... the company is doing badly and your personal billings have been way down lately, so a pay rise simply isn't goint to happen). Reluctantly, because you do feel a lot of loyalty to your employer (it's a close-knit team, and you like the work as well as the people), you've brought yourself to the stage where you're interviewing with other companies. They're really quite different to what you're used to - big, flashy receptions... hierarchical... cubicles and people eating lunch at their desks... and intense, high-pressure assignments. You've been out of the job market for some time - You was fortunate to find somewhere you liked many years ago, and basically you've stuck there since.So, the question is: What questions should/would you be asking (of yourself, potential employers, recruitment agents, and anyone else for that matter), what thoughts should be running through your head, what important points/tips/pitfalls should you be aware of and basically what things should/could I know to make life easier at what is in fact one of the most difficult life decisions you've ever had to make (I know that sounds dramatic, but we're talking about something that will have a major impact the majority of your waking hours)?
