Also, I don't have a "team" behind me -- I do everything. Opening, qualifying, meetings, closing, negotiating contracts. Your MNC interviewer has likely never had to do all of these things.

Believe me, if you're good, this is to your advantage: the team "behind" a salesperson in an MNC soaks up their time and energy with enforcing consistent data entry and deduplication across at least four legacy CRM systems, utterly spurious pipeline analysis for the benefit of the management accountants and once management decides to step in with some meaningless metrics that might have worked in another industry, you'll probably end up meeting people without either of you having any idea why you're there. And that's in addition to all the non-sales-specific inane big company bureaucracy. There's a process to follow but its generally less efficient than winging it and whilst there might be people that, in theory, do things like marketing for you, you probably spend more time fielding their questions than they do assisting you.

I like to think of it as MNCs trying to level the playing field with those who actually need to work to find the customers first.
