I applied online. The process took one day.

It was a one-day process, and they had four rounds: three technical rounds and one CTO round. Overall, if you know your basics, you would do well. I got an offer with a mere 10 to 20% hike. I refused the offer and told them I get better hikes internally. They do not even send you the offer letter until you accept it verbally. They do a reference check after that before rolling out the offer letter. I smelled conspiracy right here.

The CTO called me up a few days later, trying to understand why I refused the offer. I told him how it wasn't up to my expectations. He tried to go blah blah about how his company will grow 10 to 50x in the near future and how I should look at just growth and not money. I told him I have monetary as well as learning goals, and I need to balance them. He refused to revise the offer, and I refused to accept it. I could sense it; he got pretty annoyed, and it seemed like it hurt his ego that I refused the offer. He judged me for it, saying I didn't seem keen on learning as much as he thought. I am amused the CTO here is so idle he goes around judging people for not accepting their offer. It seemed pretty immature. It made me doubly sure I did a good job of not taking up the offer. I would advise others here the same.
