There are a few differences in the process.
Full-Time MBA students can use bid points to gain an interview with some firms. Evening MBA and Weekend MBA must be invited by firms.
The preparation is the same, but the experiences can differ. For example, Full-Time MBA students tend to participate in Campus Recruiting for internships as well as full-time positions. Also, most Full-Time MBA students have more time to allocate to their job search. That additional time and practice can impact the level of preparedness and overall Campus Recruiting experience.
