Need honest suggestion 🙏🏼

Guys I am currently working at Amazon as SPS. This job gives me in hand 26k , it is a WFH job , about 8 hours of work and sat-sun is off

Recently I have cleared sbi ja exam. But the Posting will be in Mumbai which is 460 km away from my home 🏠.

Sbi ja salary is around 41k in hand but also there are expenses like rent , food , travel in mumbai.

I am interested to prepare for this exam while working but confided about which job to keep. People have glorified sbi ja to the utmost extent as well as there are concerns regarding amazon Job since it is private.

I am unable to decide as to what to do ?

Sbi would anyways require me to work in branch, 2 Saturdays included. I also won't be able to visit my parents regulary since it will be away from home posting.

Totally confused 😕 please guide with proper reasons , I will be utmost thankful
