I saw an opening on a job portal and applied. I then received a call the next day from a consultancy, who scheduled an appointment for the following business day.

I had to wait for 10 minutes in the office lobby before HR took me for an individual written test on C. After clearing that, I attended two back-to-back technical rounds with two managers, and later another round with a group of managers, followed by an HR round.

I received the offer letter on the same day and joined two months later. This happened 6 years ago, and I haven't left the company since.

One brain teaser was unexpected, though I answered it correctly. It involved finding the one odd weight out of eight similar-looking weights, needing only two weighings.
