is it ok?

When I applied to work where I am now, in a US government office, they scheduled 4 interviews in the building, each for a separate position in a separate program. Then a fifth guy asked if I wanted to work for him, and we had an unscheduled interview right on the spot! So I had five positions to choose from. I chose the guy who I sensed was more relaxed and would not cause me problems. For instance, one guy expected me to take classes to increase my skills. It sounded like a lot of work outside of business hours, so I eliminated him. Another guy looked like he did not enjoy his job, so I eliminated him. And so on. One guy said I would be doing mostly production work, whereas another guy said I would mostly be doing research. So I chose research.

I did not think too deeply about the type of work, as long as it was math. I never thought I would be there for that long. Well, 18 years later I am still here! The guy who hired me left after 10 years for a better job, and then retired a few years later. My current boss will retire in a few years, and his current boss retires on Friday! But I do not want to be a boss, so I will not try to move in when he retires. No, just give me some neat math to do, and leave me alone to do it! Keep the annoying federal bureaucracy off my back and let me do some math! LOL! (said by a person who is part of said bureaucracy!)

But if you think you might want to work where I do, fagetabouit! Trump just instituted a 90 day hiring freeze! And after they plan to reduce the workforce by only hiring one person for every 2 to 3 who leave. Fun times! And more work for me! Ugh.

The fewer breaks in employment the better. Thus, use "the present".

If you're still employed, choose the present option.

And yeah..it's perfectly acceptable to apply for multiple positions..as long as they're not like Receptionist vs Vice President ;)
