HCLTech Senior Analyst interview questions

Long process, interview was conducted for 3 days which had 1 technical written test followed by 2 interviews. After 15 days i was confirmed about my selection, Joining process is the most hectic part where they all the documents related to education and previous employment and took one month to complete some verification after which i was provided offer letter. Strange thing same verification procedure was followed once i joined company and started to work.
