Infosys Technology Analyst interview questions

first i was contacted through phone and got webex interview invitation.(i did multiple interview ,I dont remember how many). Finally contacted by a tech lead and got notified that i am selected for employment and got the orientation date. So based on these information I gave a 2 notice and waited for the orientation date but they just disappeared without any explanation.Lost my job. I don't believe this really happened to me. The most FRUSTRATING experience of my life.

Weekend drive for the role of Technology Analyst in Data and Analytics domain. Two levels of technical rounds followed by HR Technical rounds were pretty easy with basic questions. First Technical was telephonic and second was F2F
