The interview will be at short notice.

Expect approximately two to three technical rounds and two management rounds. If successful, the final stage will be an HR round to negotiate grade and pay.

Multiple technical interviews are designed to identify the best candidate and can be conducted by different Business Units (BUs).

HR representatives may negotiate assertively, potentially stating that today is the last day to finalize the offer. It is acceptable to take a day or two to consider and finalize the offer.

Training and assignment allocation are based on the offered grade. With an assigned grade, it will be challenging to prove your capabilities for the next level.

Grade movement and promotions are very difficult, leading to considerable frustration among many employees.

Some of the questions the interviewer asks are college-type and may not be relevant to the job. It looks like the interviewers prepare themselves with questions available online. I think most of them are applicable for a fresher.
