The Hr response quickly after you have been shortlisted for an interview. The interview process reqiured two step. First is the online interview and second is onsite interview (maybe need to depend the plant or Hr)

First interview was the technical interview by engineers and one manager, need to asnwer some easy technical questions, will ask what difficulty faced in school, very friendly and it's okay if you answer the technical question wrong (but need to show you understand the principle)
