Lithium Technologies Software Engineer(Internship) interview questions

Round 1: 15 minutes cognitive test similar to a IQ test along with a 15 minute personality survey. Round 2: 15 minute cognitive test but with webcam on in front of recruiter. Round 3: Leetcode easy Java algorithms/data structure question. I solved it in 50 minutes but was told by hiring team that they no longer wanted an intern for the summer. I think for a company to suddenly on a whim say they didn't want an intern for a summer at all that they started looking for since May shows how little they know about recruiting season along with how they decided to use a IQ test to filter out candidates. While they could be reliable, they do not correlate to good programmers/engineers in general at all. I spent about 1.5 weeks on this interview process as well. Compensation was said to be $20/hour. Quite low for a high bar in general.
