Lenovo interview questions

I had an internal reference with a recruiter and was requested to interview with them a couple weeks later. They mentioned, at the end of the interview, the next step would be to narrow down the candidates and have half day site visits. There was no response. I followed up with the recruiter and hiring manager. They ghosted me. A month later I received a request to fill out a survey about the interview experience.

2 technical rounds, a Director round and an HR. It was mix of Remote and On site interview. The HR delayed the process. But went well for me. Fundamentals of data structure, the problem solving skills, C programming
