I applied via a LinkedIn job post, shared my resume and was asked for a first interview with HR. After that, I was asked to schedule another interview with the tech team and present a mock-up lesson on a subject that was previously shared with me. The process was very pleasant, they gave me clear instructions on what they expected for the mock-up lesson and gave me a couple weeks to prepare. The responses from HR were always quick, just a couple days later after each step.
