I'm currently looking for a job as a software engineer, and I've received a few offers I'm choosing between. One of them, from a company I'll call Alfa Corp, is much better, so I'm trying to use it to negotiate with another company, Bravo Inc. The person I'm talking to from Bravo says they'll see what they can do, but Alfa's offer is so much better that they expect their manager at Bravo to ask for a screenshot of Alfa's offer letter. This feels weird to me, but I'm not sure. Is asking for a screenshot of a competing job offer normal behavior? Does it depend on the industry? And if it isn't normal, is this something I should be willing to do?
This is an unusual and unorthodox request. This isn't something I would comply with.
That being said, you probably risk losing the offer from Bravo if you don't comply.
So it's down to a personal decision. Are you willing to lose the offer from Bravo if you don't comply with their request? If you are, then deny their request. If you're not, then comply with it.
I would say it is not all that common.
Before a company advertises a position they usually do a bit of research to see what other companies are generally offering for similar positions, and then set salary ranges. This means that it shouldn't be all that common that an applicant has an offer from somewhere that is so much higher that they would need to see evidence of such an offer.
Having set a range for the job also means that the company has decided the job has that value - so it is unlikely that they are going to increase their offer beyond that range. I'm surprised they asked for evidence - the typical response would be "well, we can't match that, our best offer is $lower" and they will likely rescind the offer and go to the next candidate.
As for should you do it - I wouldn't. I would just accept the better offer from the other company.
