How to leverage Linkedin data for Company/Position Analysis



I am trying to do secondary research for a position in a company using linkedin.
Questions that I am trying to answer are like:

  1. What is the average work experience of people in the position?
  2. Can I get clear insights about their educational background?
  3. Can I categorize them in buckets like IIT-ians, NIT-ians, etc.,
  4. Can I get any insights about the average time people in that position are spending with the company?

Any help in this regard would be appreciated. TIA
