Hi guys, I've been reading this post recently and have got some queries hoping sifus here could clarify for me.

1) im an acca student and will be taking my last 2 papers this coming june. Should I start appying in may if I wish to start working in july as been told by one of big 4 recruiter to apply 2 months in advance.

But at the same time, I also worry that I might lack sufficient time to prepare and revise the IAS and types of questions that might be asked should they would call me up for interview and online assessment etc (let's be optimistic) as the forumers say ey and kpmg/deloitte would respond in a week time since im preparing for my finals now.
How long does it usually take from initial application to issued of offer letter?

2) is it more difficult to get into penang branch as compared to kl due to it being regional and therefore has lower turnover?

Would working in penang big4 limit my possibility of working overseas in the future as the employer may discount my experience perceiving regional office is smaller and hence lower exposure?

3) let's say I work for 1 year and leave (work holiday in other country for 1 year), is it still possible to get back to the same co or other big 4? Would this make my resume look bad to hr as they may think I cannot bear the pressure in big 4 or whatsoever? (Cuz it's better to have worked up to 2yrs and leaving as a senior?)

4) the last option for me would be to go for internship in one of the big 4. Upon completion of internship, go for work and holiday for 1 yr. After that, come back and start applying jobs. Is this feasible? Would I stand a lower chance than b4 cuz I have 1 yr gap since I completed my studies and may not be favourable to them cuz my memory not fresh anymore? Lol

Im sorry to bambard u guys with so many questions.
I really need yr help, thank u in advance.
