Schneider Electric interview questions

I could'nt clear technical interview so I am writing the question which were asked in technical interview only tell me about yourself? asked about my family background? what are different types of DC machine? if you go to buy a transformer what specification you tell the seller? you have 1000KVA transformer what will be the current? you have 10 HP induction motor what will be the current ? one thing to keep in mind that difficulty level could vary it depends on the interviewer and role they are interviewing you for so once check the linked in profile of interviewer if you get to know his name before interview. Also whole process for me and my friends was online.
