I am applying to a MS in a STEM degree (Business Analytics or Data Science) at some pretty competitive US universities (domestic applicant).
I have done a lot of different types of work during and after my bachelors program (coursework completed in 3/17), in a large variety of projects and teams on many different time tables and employment statuses. I'll have a separate question I'll be asking in relation to my freelance work after the period in the image below, but I wanted to see what from my usually listed items on my resume I should consider factoring these into the question "How many months of work experience do you have?"
There are mainly 3 questions here,
How should I tabulate months of experience based on the man-hours I've through put on these projects?
Which of these projects would be considered something I should not count towards a question like that on my graduate applications?
Is there an implication that I should be focusing on post-graduate work experience for a question like this or any other conventions I should be cognizant of?
