Datadog Team Lead interview questions

The 1.5 month process started with several experience, personality and technical phone interviews and ended with a 4 hour on-site interview. After the on-site, I immediately sent a follow up email thanking the recruiter and the team. I received no response to the thank you email. No sweat, I know they are a busy company. Following the thank you email, there was a 2 week period of silence from Datadog. No emails, no phone calls. After the first week, I followed up with the recruiter asking if the interviewing team has made a decision. I received no response. I waited another week and sent another follow up email. 30 minutes later, I received a call from a DD recruiter (a different one) letting me know I didn't get the job. The reason they gave for the delay is that they simply forgot to follow up with me. Having applicants wait 2 weeks after an onsite, only to be declined is unacceptable for any self respecting recruitment team. A hiring team is the face of the organization, and showing such a lack of empathy is not a good look for any company. The on-site interview consisted of a simple string parsing question, a standard system design question, and 2 behavioral interviews. I was expecting tougher technical questions, especially for a company that operates at their scale. The behavioral questions seemed as though they were picked randomly out of a hat, and did not seem applicable to the position of team lead.
