It's essential to manage your time effectively, maintain transparency where needed, and prioritize your health and well-being. Striking the right balance ensures that you can fulfill your responsibilities without compromising the quality of your work or your personal life.

First, what you do during your non-work hours for any employer is your business - not theirs. They don't need to know what you do unless it could get them into trouble. (For example, you work with children but your second job is in the adult entertainment industry.) All your employer/boss should care about is that you are fulfilling your obligations. You are showing up to work on time. You are completing all of your tasks without too many errors. You are a team player and you keep everyone in the loop on work-related stuff. If you are checking those boxes then you are an awesome employee/contractor and they should be pleased to have you on the team.

Second, you need to make healthy choices. You should not work two full-time jobs (~80 hours per week). You will burn out and start doing bad work. You should not work two jobs with overlapping schedules. You cannot be in two places at once and they will both fire you when (not if) you get caught. You need to have a clear mind. You should not do one task and submit it to both employers. You should not lie or steal ideas. If both jobs are part-time and they have different schedules and you will get enough sleep, there are no issues for your health. If you are only working for one company at a time at the times you agreed to do the work then you don't have that worry hanging over you like a dark cloud.

For the job interview, you can talk about your experience - even if it is your current job. It is NOT unusual to interview someone that already has a job. The person interviewing you may ask about how that job might conflict with the role you are interviewing for. That is to be expected and normal. Be honest!

For your friend and current employer, there is nothing to bring up unless it looks there will be a conflict with the schedules or the companies are competitors. It is your personal time to do with as you please. It might come up in general conversation like, "What did you do this weekend?" No reason to lie about it, but no reason to bring it up unless the company you currently work for says that you have to advise them of a second job. (Might want to check the employee manual, but there probably is no employee manual.)
