ENGRTOMBA2018 is a recent Kellogg alum lol.
You are probably the only one in this whole thread who did not go to business school.
Also, anecdotal evidence about I know this guy who went to BCG or that guy who went to Strategy& does nothing for the post.
Anyway, back to the question.
Several PT students get comparable opportunities as FT students, especially during full time recruiting. However, making the best use of those opportunities are tough.
One of the best ways to get a consulting gig is through the summer internship and you will miss out on that most likely if you are a PT student. Also, there will be many recruiting events throughout the week (which often leads to getting an interview and a positive impression with firms) that might be tough for someone who has a full-time job.
Now that your goals are in tech with a client service focus, you are most likely looking at sales, business development or marketing roles. In my opinion, the FT or PT differences for these roles would not be that significant and you would not lose a lot of money in opportunity cost.
The best path forward is to figure out the roles and the companies that you actually want to work for and start networking with those people from Kellogg and Tuck to see if there will be a big downside if you are in the PT program.
