of course its important but its not everything. you have to consider annual increment and exit opportunities as well. look at signing on, you can command a very healthy starting salary of almost 5k if you get good honours, but the increment is like kachang puteh and the exit ops are quite limited.

compare to the big 4, starting pay is 2.8k only but salary can rise relatively fast and exit ops are much wider.

moral of the story: salary is important but not everything. don't be blind like some dumb dogs who keep saying "THEN WHY HR ASK FOR LAST DRAWN SALARY". employers are as concerned about what skills you gained from your previous jobs as how much they might need to pay you.
