IBM Associated Software Engineer interview questions

I first received an online language test. Then got invited for an offline coding round. It was a fairly average-level question with 7-8 test cases on the HackerRank platform. People who passed even 3-4 test cases got selected for the next round.

A recruiter reached out to me about scheduling some time to speak. They just scheduled a time without even confirming my availability first. Thought it would be an initial phone screen, but was a technical interview with someone different than I was emailing. The lack of communication and information was disappointing
