Without doing almost much of work my manager changed my title from Tse to SE(Software engineer)

I don't wanna be harsh but if you're in a service based company, don't get too happy. It's part of the procedure. My friend is in persistent for the last three years, now is a sr engineer, still doesn't know typescript/next js.

If you want to improve, solve some bugs, write test cases, help maintain documentation.

Don't drop the manager's "tea" :p

What did the T stand for though?

Is it a promotion? If yes, take this opportunity to grow my friend.

I joined before 10 months by the way
