Zalairi's journey

I recently had an interview for my ideal job and I'm really excited about it. However, I also have another job lined up that starts training next week. I'm feeling a bit anxious about the timing, so I want to know how to ask the interviewers when I can expect to hear back from them. I want to make sure I give them a sense of urgency without coming off as too pushy. Any advice on how to phrase this during the follow-up?
