Wipro Technical Lead interview questions

First round one hour technical interview. I was interviewed for Elasticsearch, so mostly about search engines and indexing related questions and Java collection and design patterns. Second project manager discussion, discussed about previous project experience and technical difficulty faced Both round cleared and HR confirmed that also ask me to don't take interview but they haven't replied for three weeks by the time I placed in other organisation Three weeks later they came back and ask me join but I didn't accept it.
