Waiting games

So I applied for a job on April 19th I got a call the next day to come in for an interview Monday April 23 it went well the lady told me she’s going send me a link for a background check then after that I would do a drug test an training it’s been a week and she still hasn’t sent the background-check yet 🤔🤔 btw I called and left a voice mail just saying my name and saying I have a question about the background check they haven’t got Back to me uhh should I forget this job and apply else where ?? My sis in law applied at this place a week before me and she said they took long to send the background check she’s still waiting on them to call her for the drug test but the whole waiting is making me impatient 💀 when I have other jobs wanting me to start ASAP but I really wanted this job I don’t want to start other places then this job calls me back btw I do have a full time job I just want a different job closer to the new town I’m going be moving to idk what to do 😩😩😩😭😭what’s the longest I should wait on them what should I do ??? This job sounded to good it’s close to the place I’m move into and the hours are good idk 😐
