Post-MBA consulting assoc around ~S$12k+ per month at
MBB, plus a small bonus, maybe S$160-170k per year
IBD associates (M&A etc) around ~$18k per month, half a year bonus at least, if not more, so at least S$320k a year. but most IBs don't hire from this route these days
Business / corporate roles in large tech companies probably makes sense. they are hiring a lot these days and I suspect the pay will be comparable to consulting.
