I am applying for postdoc positions in the area of Mechanical Engineering (Robotics) in US and Europe. Often times I see that the reference letters are required to be submitted at the time of application and it is mentioned that only complete applications will be evaluated. Does this mean that I am expected to collect electronic versions of reference letters from professors, which I would need to submit along with my application? How can I waive my right to not review these letters?
What is the typical way of submitting reference letters for a postdoc application in the area of Mechanical Engineering (Robotics), since the application process is not so structured?
