I have given 2 technical Interviews and 1 HR interview for getting selected as assistant system engineer. Before interview there was a OA in which we were asked about basic aptitude question and c basic questions and 2 coding question to compile and get proper output.

The interview process consists of three stages. The first round is an Aptitude Test to evaluate logical reasoning, quantitative ability, and problem-solving skills. The second round is a Technical Interview focusing on core technical knowledge, practical understanding, and project experience. The final round is an HR Interview to assess communication skills, cultural fit, career goals, and overall suitability for the organization.
