Datadog Premier Support Engineer interview questions

Absolute joke of a company to apply for. After 6 rounds of interviews (All online) including passing 2 technical (1 hackerrank test and 1 online screensharing session with the hiring manger and other team members) there was no offer as they said they did not see me to be a 'cultural' fit. While I insisted on doing the final rounds onsite, apperantly because of some 'confusion' from one of the recruiters, 3 interviews were set online back to back in just one days notice and they want me to know their company values and culture online and judge if I am a good fit or not, also online! I mean let's be all robots and just answer everything online whatever the panel loves to hear. 7+ hours of my valuable time feels like a complete waste of a time! Such an immature company and recruiting process.
