Ashvyn,
while the others here have given some valuable advice, I would like to add my 2 cents worth.
I was in a similar situation as you a year back.
I am engineer and MBA, was working in an MNC bank and was making decent money but was dieing in the corporate job.
I thought about it a lot and made up my mind to switch careers and fly professionally.
Let me tell you its a big risk and you need to make sure this is what you want.
Once you get into flying you need to give it your all because there is tremendous competition for each vacancy out there.
First things first, clear your class 2 and class 1 DGCA medicals before you spend a single cent on flying. Make sure you are fit to fly.
As rightly said above, flying is not the hard part; Funding and written exams are.
However, once you are certified medically fit, you can start both theory and flight training simultaneoulsy.
If you do decide to quit your job and decide to train full time, it will help to do both concurrently because they are complimentary.
Some flying experience helps you grasp the theory better and the theory will help you make sense of the aircraft and systems you train on practically.
Also, there is not much difference in cost for flying training here Vs abroad.
But, give a wide berth to philippines. Consider USA, Canada or Australia.
These 3 have the highest training standards in my opinion and Visa is relatively easy for all 3. Plenty of people on this forum will be able to suggest good schools based on their experience.
I have nothing against Indian Flight schools but their programs are less flexible and they have fixed batches like a college. Plus they charge fees upfront (even if you pay in installments, the school always holds the upper hand Because they keep more money than you have flown worth, always.)
Abroad, the flight schools have a continous running course where you join any day of the year, are assigend an instructor for your training needs and proceed according to your desired pace; And you pay as you fly, after every flight so you hold the cards and can switch schools or demand some changes if you are not satisfied.
I found that more appealing and so chose Canada for my training.
These are my inputs based on my research and experience.
The final choice is yours.
Feel free to PM me if you have further querries.
