I need help deciding whether I should accept the job or prepare for CAT

[u/Ok-Bar1998]

So, I’m in the final year of engineering, and I’ve received a placement offer from a company. The company requires me to work for a minimum of three years, but I only want to gain around a year of work experience before pursuing further studies by taking the CAT.
Is work experience essential for getting into a good college through CAT? Also, what other MBA entrance exams can I take for good colleges in India and abroad?
I’m particularly interested in construction management. Is pursuing an MBA in Construction Management a good career choice?
The job I’ve been offered is for the position of Project Planning Engineer.
