The hiring authority at Panera Bread would like to know how much lead time they have to extend a job offer. If you are actively interviewing with other companies, tell the interviewer your current status and expected job search progress. Be honest and transparent with the interviewer - they will appreciate it! If you are not actively interviewing with other companies, you can simply tell the interviewer that you are selective about the applications that you make, and you are most excited by the idea of joining Panera Bread.
