Had multiple admin positions, all applied online. They contacted me via email or phone. I was interviewed by all the managers of the department. If you applied for a position that is hiring multiple candidates (10+), they might have HR do the interview. Some may start you off with a typing test, where you need to type more than 45wpm. For the interview part, they mostly ask behavioural questions that they choose from a list. Most common ones are about teamwork, conflict, time management, or dealing with a difficult client. These questions are often selected from a list; just search for HR leads based questions. Most positions would ask around 7 questions, usually not too difficult, but some managers do ask you to prepare an elevator pitch beforehand to spice things up. They will tell you what to expect. Your answers are then scored, and they will choose the candidate with the highest score, and if candidates have the same score, they will choose based on seniority.
