There are people, who spend 6 to 12 months to prepare for FANG interviews. Even kickstart programs for interviews last two months. There is a huge group of people who spend at least 6 months for top pay, etc.

As he pointed out, after 1 or 2 months

Good point. Unfortunately, I've had some personal stuff come up, and I have not been able to put as much time into prep over the last two weeks as I thought I would.
