Yes, sounds great. Make 10K more out of the gate. And if you're finding it tough to land a job right now, what a DEAL this is! You're employed! You're really needed since the number of COBOL programmers to support legacy systems are dying off (figuratively and literally).
There's the catch. They've got you. You don't know it, but they know it.
Next year, your fellow grads who got jobs are learning TONS of new things, other skills. Team building, real life design. Team leadership. They're getting mentored perhaps. They'll make their way up to intermediate, then senior developers. Maybe into architecture.
But you're still slogging through COBOL code. Supporting legacy systems.
And they can't afford to lose you, so your company (A Bank most likely - not the fastest moving group in the world (and I know since I've worked for three)). So you're still COBOL programming. But, y'know, thanks for the effort. Here's a 2K bonus.
Uour friends are now 2 years along in their careers, they're moving to new jobs, making 10-20K more since they can show job experience, skills experience, and real-life development qualities.
You're even or a bit behind, pay-wise. But they're going places. You're about to stand still, career-wise.
In a year they shoot past you, and that's that. You're standing still. Cost-of-living increases if you're lucky. But hey! We at the bank really appreciate it. So here's a nice mouse pad, and the latest patch release for COBOL on the Z-Frame.
So, no movement here. What to do? I know!! Other companies need COBOL programmers. I'll play the field and see who will throw me more money.
Great. You make a bit more money. Doing EXACTLY the same thing, somewhere else, with little if any career growth. It's possible you will always have a job, since COBOL is entrenched, and not going anywhere. But that's all you'll ever do. That and cut 1650 reels with your teeth.
Don't Do it. It's a trap.
