Brutally honest career advice needed: CAT/GMAT/GRE vs staying in industry?

I'm at a point where I need to decide the next few years of my career, and I'd rather hear harsh truths than comforting advice.

**My profile:**

10th: **87%**

12th: **81%**

B.Tech (CSE): **8.7 CGPA**

Category: **OBC**

Work Experience:

1 year **internship** at a Canadian startup

1 year **full-time** at the same startup

4 months at **Blinkit** (currently)

**Long-term goal**: Move into strategy, product, operations leadership, or consulting.

**Since I have low grades in 10th/12th my dilemma is:**

\- Prepare for CAT and target IIMs/FMS/XLRI.

\- Prepare for GMAT/GRE and target ISB(PGP)/MBA programs abroad.

\- Skip the MBA for now and focus on switching jobs and growing my career.

I'm not looking for motivation. I want realistic feedback.
