93%ile in CAT, should I join KJSIM? Advice appreciated.

About me: GNEM, 10th- 95%, 12th-96%, UG (Arts) - 69%, 3 years gap.

With 3 months of prep scored 93%ile in CAT & 94.9%ile in XAT.

Despite my interviews seeming decent to well, I could only convert KJSIM and single digit waitlisted in IRMA. (Clearly there's something wrong i'm doing in GDPI)

My question is: Should I join KJSIM this year for ~12 LPA later OR get a (very) low paying job now and prepare for CAT, XAT again?
