E4 is Senior Manager and E3 is Associate Director.

The top one usu the turnover rate is really low so very hard for a dept to have so many Associate Directors so most ppl get struck at E4 until near retirement where they maybe promoted to E3.

the only good thing about NUS is that workload is generally not so bad (even when compared to CS) and there are down periods. food there also quite a lot of variety etc. etc. and thus ppl who worked a couple of yrs in NUS will find it stress to switch to a faster pace environment so they rather stay and dont really care about pay and progression.

very good for working mothers and fathers who would want to spend time with his kids
