No company standard for interviewing. It is up to the hiring manager/group. After a brief telephone screening, there is a fairly standard, in-person, tech interview lasting about three hours, including speaking with hiring manager for perhaps an hour, then various QA, development, and possibly design team members for thirty minutes each. Not usually multiple rounds of interviews for QA engineers.
