After the interview, you will expect either to receive a job offer, a notification of rejection, or no word at all. Occasionally the job offer is extended at the end of the interview, but most offers come afterward in the form of a phone call by the hiring manager or head of the search. Unfortunately, sometimes candidates who are not chosen are informed of the decision long after it is made, or they receive no notification, which leaves them hanging. For this reason it is a good idea to inquire during the interview about the timeframe for decision-making.
When you receive a verbal offer, during this conversation the hiring manager will likely go over the basics of the offer (e.g. salary, start date). Be prepared to take notes and ask questions. Do not feel pressed to accept or decline right away. Ask that the offer letter be mailed or faxed to you, and request time to consider the offer carefully. Several days to a week is a typical length of time for decision-making; more time may be acceptable, depending on circumstances.
Keep in mind that verbal promises are not formal job offers. Arrangements sometimes fail to pan out at the last minute, putting job seekers back on the market. Formal offers should be put in writing, defining the salary and terms of the position, including start date, benefits, and other relevant details. Sometimes in sectors beyond academe you will need to negotiate and either accept or decline an offer before receiving a formal written offer letter. In this case you and the employer proceed in good faith, but you should still request a written offer for your records.
Following are basic guidelines on evaluating and negotiating job offers beyond academe. GSAS Career Services holds a program annually on the topic. Check our Current Events for a schedule of upcoming programs.
