I'm a big believer in that it's really no big deal to wear a diaper.. to anything really. But there are two school of thought that I go to on this.
When it comes to careers, I've always believed that - when at work, focus on nothing but work. This includes setting aside your hobbies, relationships, your weekend, and even your diapers, if you must. Having focus and diligence for the hours you are at your job will make you a good worker, which in most cases means you will move up in your field and thus, your life. Moving up in life will make a lot more things possible for all of the things your set aside while you are at your job; More resources for hobbies, being able to move forward with your relationships, do more on the weekends, and of course, expand your exploration of your fetish. But if you let other things get in the way, especially in the beginning, you may not find yourself to be as lucky.
With that said, is it really that big of a deal to wear a diaper privately and discreetly? No. Look, here at Adisc, we are a support community. Most of us are will advise against anything that might complicate your life. We all have had our share of complications with being a diaper lover, adult baby, or both, so we will always suggest to keep diapers out of the more important or serious situations. This would be the same thing if you came here off topic, and expressed wanting to wear / do something in a job interview that others competing for your position would not do, and possibly have this advantage over you. Basically, we all just want you to get the job, but that doesn't necessarily means that wearing diapers to situations like these is 'wrong'.
Without coming here, I'm sure you could have still worn your M4, gotten the job, and succeeded, but only you know your level of focus and diligence. I wear diapers on the job and it's never been a problem, so as long as you feel that your AB/DL side won't interfere with being a good worker, a comfortable person to work with, or isolates you in any way both mentally and physically, then there is nothing wrong. Just always remember to be discreet, smart, and respectful. In some situations that is possible, in others it isn't, so you be the judge of that and on whether or not any of these situations will hinder the ultimate priority: your job and career. Remember, career (and your spouse & kids if you have them, but the career usually works in tandem if you are the provider) comes first so that you can succeed in all things in life.
Good luck on the interview! Keep us posted.
