What they ask in interview in Big 4 ??

Well, when i attended one of the big4 interviews, they asked me a lot of questions in accounting (including AS), audit, law (from what you studied in IPCC, of course). But this was before the results were declared.

You'll get very good exposure and also the brand name of doing articleship in a big4 firm. Also the work culture will be very good. But you may have to put in longer hours of work during peak audit periods.

what should i select for articleship in Big4 - statutory audit or taxation?? please let me know asap !!

Well, are you into tax or not? I cleared my tax group earlier, and only managed to squeak thru in Tax. I know nothing about Tax currently. so Tax is a big no-no for me lol.

Better to go for Statutory Audit, since that's where you'll get exposure to all the audit processes and practices- you'll get to know how an audit is actually done. You may have less pressure in Tax, but i don't think you will learn what you need to know.
