LiveRamp Technical Support interview questions

The recruiter reached out to me via LinkedIn. We scheduled a time to speak for a phone screening. Next, I spoke with someone in the same department I was applying for. The last step was a 3 hour in-person interview, including a 20-minute presentation with Q&A afterwards. The in-personal interviews were with four people, 30 minutes each. At the end, I presented a PowerPoint on skills and strategies of how to improve the support role. At the of this process, I was not offered a position, nor was I told via email or phone that I did not get the job. I ended up having to email the recruiter to follow-up with no offer. He claimed to have left a voice message but I never received anything. The most disappointing part of this entire process was the lack of feedback they were not able to provide post interview due to their company "policy". Never had I interviewed for a company that made me do the most work only to provide ZERO feedback after. I'd be careful about what you present to this company, they might just want to steal ideas.
