I'm expecting a job offer from Company A sometime this week, and I also have my first interview with Company B. There's a second interview after that before they make a decision. I'm not sure when the Company A will expect me to get back to them on the offer. I like Company A, but Company B has some significant advantages that I cannot ignore.
What should I do if the Company A expects a response before I get an answer from Company B? I informed Company B that I would be dealing with another offer, but they didn't directly address that when they scheduled my interview shortly after that. I feel like I have to wait for Company B, but if it goes on too long it's possible that I could end up with neither job.
If A want an answer now, be firm but polite. If they want you they'll wait. If they think you are a dime-a-dozen they won't. Better to find that out now. In the future make date X clear from the getgo.
