Arrive 15 minutes earlier. HR was professional and friendly. Interview got delay due to change of location. Originally 2 interviewers were arranged, but one of them couldn't make it. Interview last for 30 minutes as the interviewer that present did not prepare prior to that (just roughly go through the resume right on the spot). Question being ask was job responsibility and type of equipment known. Interviewer run out of question after 10 minutes. The rest of 20 minutes was interviewer answer question ask by me.
