New joiner here (C3A). What is Wings? Is there a salary hike if we clear it?

Wings2 is more for old timers with comparatively lesser pay.

New joiners are significantly highly paid already. Efforts wont be worth the hike you will get. Dont waste your time.

Wings is a career growth program. Clearing it may lead to a salary hike, but the percentage varies. It's a good opportunity for learning and advancement.
