I got in through an employee referral. The first step was a coding round with questions ranging from beginner to advanced levels. A week after submitting the written assessment, I received an email inviting me for a 1:1 interview.

The on-site interview took place on December 3rd and lasted the whole day, consisting of four rounds. They covered all the topics in C, and I had a really great experience. The interview covered almost everything, from post-increment/pre-increment and arrays to pointers, strings, sorting, data structures, algorithms, operating systems – literally everything.

After another week, I received an email from HR stating that the interview was positive. They sent a questionnaire regarding usual HR matters: compensation, title, notice period, and so on.

However, the HR process has been very poor, giving a totally negative outlook. To date, whenever I contact them, they say it's still in process. It's been almost 40 days, and I still haven't received an offer. I'm still waiting.
