I applied through other source. The process took 8 weeks. I interviewed at Missouri University of Science and Technology (Rolla, MO) in May 2016
Interview
We have to e-mail professors for vacancies attaching our resume. They'll revert if interested. Then we have to pass a teaching workshop to officially get the offer. The workshop results are forwarded to the department in which we are supposed to be employed. The department then places the students according to their grades in the workshop into the vacancies available.
