I am in the process of getting licensed in multiple states and my employer requires 35ish but won't stop pharmacists from getting licensed in every state and U.S. territories.
Getting fingerprinting done and documents notarized is actually the most difficult process.
Also, some states require in-person interviews (some are done remotely now but others still want you to fly in), which can also pose difficulties.
I was originally concerned about MPJEs but quickly realized that it is not that bad.
MPJEs are pretty repetitive and I am currently only studying few hours the day or two before each MPJE since I pretty much got the federal law down and just need to memorize the state specific details (the NABP annual survey on pharmacy laws is an excellent source if you just want to glance at state specific laws).
I even dare to say that you can pass any state's MPJE if you just know your federal law well and make educated guesses on state specific stuff (other than time lines and day supply limitations which needs pure memorization, the intent of rules and regulations on many topics are pretty similar from state to state).
My employer pays for all the fees associated with acquiring and maintaining licenses, any study guides pharmacists wish to purchase, pre-MPJEs if pharmacists want to take them, allows the exam to be taken on company's time, and pays bonus per each new license acquired, so I don't mind taking them.
Also, having multiple licenses may come in handy if you ever plan to move out (I know my Guam license will be handy in 30 years when I want to spend the rest of my remaining years there!) and getting these at the expense of your employer is good opportunity in my opinion.
I personally would not have spent all those application fees (it is not just a single fee but multiple fees for one state that can cost near $1,000 for certain states!) nor forced myself to study on my own time if it wasn't for my employer requesting me to get licensed, so I think it is a win-win for myself and the employer.
