I was also told during my MBA program (several years ago) that accepting an offer and later reneging it for another offer was considered bad etiquette (I guess they wanted to preserve the image of the B-school and its candidates, so they actively discouraged this practice. Which makes sense).
However, since I'm applying for a mix of MBB and T2 firms as an experienced applicant several years out of B-school (US), is this practice still detrimental? Or is accepting then reneging an offer (if a better offer from a higher tiered firm comes along) just considered a cost of making a business decision as an adult looking to maximize their option's value?
Obviously HR would frown upon this and you might get blacklisted from reapplying to that firm again in the near future (potentially worth the risk imo).
I know you can politely ask for a decision deadline extension if you receive an offer, but if there isn't sufficient overlap between the two firms' interview dates, how do you guys feel about accepting the 1st offer by the decision deadline, while you interview and wait for the second decision?
I know some people I've cased with have done this exact thing, but I'm still a but unsure. Any thoughts/personal experiences?
