1 year vs 2 year masters

[cookderosa]

The bigger worry here is the request for the three or four-year masters!!!!

Perhaps, this company value's a program of longer length based off of poor experiences with candidates coming from programs under two years. This would fall in along the lines of a company requesting a traditional brick-and-mortar master over an online master. This request is not one that I have seen but would not be the wildest position for a company to take.

But the "time to complete" isn't really a thing. For instance, if a company asks for a "4 year degree" they don't mean a degree that took you 1460 days- they mean a bachelor's degree. A master's degree can be taken at full or part time speed, the length to complete wouldn't change that it's a master's any more than doing a bachelor's in 2 years is "less."
Whoever wrote the ad is uninformed - I'd probably not apply if this is a small company - red flag. If it's a very large company, you just have to get past HR.
