Upcoming Test - Need Opinions!

Hey all. Newcomer here and just wanted to get some feedback from some of you guys about my situation.

I am hopefully going to get hired as a paid intern at a bank soon. I had my first interview a few days ago. I was told they would call me back for a second interview if i was picked (which im expecting to be sometime next week). I talked to someone who used to work there and they said they do drug test but you are allowed to schedule it which is nice, but im not going to schedule it too far away from the date they mention it just because i dont want to come off as suspicious. Im shooting for 15-20 days of being sober before the test which shouldnt be a problem. So here's some info abut me and my usage:

Physical State: I am a 5'11 athletic male weighing roughly 145-150lbs. I am pretty active and workout when i get the chance (usually a few times a week) and i also have a great metabolism.

Marijuana Usage: Today marks day 4 of not smoking. Before i would usually smoke a bowl a day. There was sometimes a day where i wouldnt smoke at all but this wasnt often.

Ever since day one of being sober, ive been drinking at least 32oz of cranberry juice and taking my vitamin supplements daily (Which include vitamin B and Niacin) and will continue to go through this routine everyday until the test day comes. Ill also more than likely get an at home test sometime before the test date, but i just wanted to get some opinions from you all to see what your thoughts were and maybe some further suggestions on cleansing. I know the drinks dont work and i dont want to have to use the synthetic urine if i dont have to. Thanks all!

I would get a 10 pack of THC tests from Amazon for about $9 to check your progress. I couldn't find any in the local stores other than the 5 panel kit, which was around $20 for one test. If you're consistently failing and this job is worth the trouble, I would go into it with the intention of subbing with real urine. The only risk is getting caught with it, but you can even minimize that with extreme measures...

Diluting would be plan B but it takes a serious amount of effort to pull that off. If it isn't done correctly, the 2nd test maybe observed and subbing may not be an option anymore. But if this job isn't your dream job, you may want to roll the dice.

Of course, naturally detoxing would be the ideal way to go, but it takes a really long time to expel all that THC. I honestly don't think it's realistic to be able to clean that out in that short amount of time. I'm not saying it can't be done, but it was a very tall order for me. I have been smoking for years and came to grips that it's going to take 30+ days to get clean.

For me, subbing worked and it was the most stress-free. Ive read a bunch of posts here where people were anxiously waiting for the results, but when you know the urine is real and clean, you have that peace of mind, which goes a very long way.

Thanks for the reply Kobe!

This is a paid internship which isnt really necessary but would be extremely helpful and would allow me to get my foot in the door.

Like i said i have been smoking about a bowl a day for the past year - year and a half or so and have been going through the natural detox process daily which hopefully is helping. And yea ill more than likely get the at home drug tests on ebay. My local walgreens sells them for 20$ for one test which is ridiculous. If i happen to not pass the at home test, my friend said he would loan me some clean urine which is a great relief. Again thanks for the reply!
