MIT SCM program

1. SCM is a 1 year master's in SCM only. Your recruiting will be for SCM roles only (unless you do something really atypical), and you'll likely come in with SCM experience/background and use the degree to enhance your knowledge/expertise in that singular area. The LGO program is a dual degree MBA/MEng in an area of your choice. You have the added value of a summer internship where you can choose to hone your business skills, your engineering knowledge, or some combination thereof. You're not limited to SCM roles specifically, though I'd guess a large number of LGO candidates do choose to go into SCM/Operations since the candidate pool is more or less self-selective. IMO, you would gain from being with a larger group of students across the university which will give you more reach if you were to ever start/join in on an entrepreneurial venture or completely change industries but stay in an SCM/Ops role.

2. As above, I'd say job opportunities through on-campus recruiting will be focused solely on SCM. MIT on-campus recruiting is already heavily focused in finance, engineering, and operations anyways so I doubt you'd have any issue finding a job -- as long as you do come in with the appropriate background necessary for those types of jobs (though MIT being MIT, I doubt they'd accept you if you don't have the background necessary for the jobs they think you're suited for).
