I’ve had similar conversations with two friends recently. Both had full-time job offers from companies that they loved and in jobs that they wanted. But both were still waiting to hear from other companies, even though it was driving them crazy to have the unknown hanging over their heads.
My recommendation to them was this: unless you’re seriously considering accepting a new job offer, think about withdrawing your applications. This serves two purposes:
1) You can stop stressing and quit constantly thinking “What if I get the other job?” “What if it’s better?” “What if I’ll make more?”
2) You can salvage your relationship with the company- especially if you’d like to work there in the future! This saves them the time and energy of interviewing you, choosing you, and then having to go back to the drawing board to find another candidate. If I were an employer, I’d appreciate the person’s proactive and considerate action.
