Most of the time the interviewer dont know programming and shit, so most of them depends on looking at interviewee's cert. But those cert most of the time doesnt mean anything.

During my college time, my coding skill already exceeded my lecturer, where my lecturer asked me to write a solution to a question to the board(guess because he saw everybody was trying while i do nothing), i just walk to the board and code like 10-15 lines of code(linked list related, replace node). Then the lecturer just look at my code, and didnt say anything, then wipe the board, and ask everybody to copy his answer.

So what do you expect from the students of these college ? They passed their exam not because of their capability of code, but memorize, and only like 4 out of 30 subjects has direct linkage to programming, others like add maths, data structures, moral(WTF), and the FYP can be easily solved by paying(plenty of examples in even codemaster section).

So if these interviewers dont have the ability to code, they dont trust certs, they dont trust you either, what choice do they have ? Yes I agree with you, if they dont have the ability, then dont do it. But most of the time, its an order from the management, "get a few programmers, get our website and e-commerce settled", u gonna answer "no sir" ?

If you feel u arent feeling well about those tests, its a fair game, just walk away, if all 30 out of 30 of their interviewees simply walk away, then u still have a chance =P. Hes the boss in this scenario, just like i dont like "negaraku" in cinemas, what can i do about it ?
