Professors work with students at the University level. They teach the students, guide them to gain their subject knowledge. They also work on research work which is carried out by the students of their University. Professors have an in-depth knowledge of their subject and they aim at teaching their subject with same zeal to the students and thus spread their knowledge. They often times support their students in various competitions, publication of research papers and conducting research.
There is no internship, but some Universities keep some candidates on probation for few weeks.

PhD or Doctorate is necessary in the relevant field for being a professor.
For recruitment as professors in universities or institutions, it is mandatory to clear NET (National Eligibility Test) /SET (State Eligibility Test) examination.
All the post doctorate/ post graduate students in any field can work as professors. There are no specific institutes that teach tutorship course except for the test training of NET as stated above. This test is given by the candidate by self-preparation and some private institutes also provide coaching for the same.
