I am in the process of switching jobs and am wondering if my new company will require an experience letter from my previous company.
Most companies will not require an experience letter from your previous employer in order to hire you. There are several other alternatives of an experience letter on which companies agrees to consider. However, some companies may ask for one as part of their hiring process. If your new company does ask for an experience letter, you should be able to obtain one from your previous employer. Company HR would be the best person to detail you about the doubt.
