Trending @Infosys; TA to TL promotion

Nope. Atleast 2 years. Though if you are highly exceptional and have high dependency you can leverage it to negotiate exception. But it’s rare.

Until you are exceptional and has the highest dependency and good rapo with your manager no chances. You need to atleast wait another 1 year then.

Also Complete bcep level 6 exam in lex portal.

I have seen a rare cases where people were promoted to TL within 1 year of serving as TA

What’s your current package as TA now?

Depends completely on the manager

No

If you think you will get a good hike after getting promoted to TL then my friend there's is nothing but only disappointment.

2-3 years as TA If you get consecutive commendable rating
TL with 5 years exp possible

Yes you can check.
