Teradata interview questions

The interview consisted in a personal presentation about past experience, what I wanted out of the placement, my biggest achievement, my hobbies and interesting facts. At the end I has a 20 minute individual interview with questions based on the experiences from my presentation.

(This is from 2017) I had applied online for a new grad position. Interview began with a phone call from a recruiter who asked some questions about me, my experience etc. Received a multiple-day coding challenge next which was to design a REST API for a data dump they provided a link to. After submitting this, I had to follow up with the recruiter after 2 weeks to go ahead in the process. For the onsite, I had around 4 rounds (3 technical and 1 with the hiring manager). Overall they went well, but I wasn't able to answer some questions about scalability since I had no prior experience. After the onsite, I was told to expect a decision in a week. I got ghosted by the recruiter for around a month, before being informed they were planning on extending an offer. However, the recruiter again went AWOL and I got a call after a month informing they were not proceeding with an offer since they wanted to hire someone more senior. Overall, the process 2.5 months and was just time wasted.
