Interview process started in Feb-18, I received call from company for F2F round. 1st round of interview gone well and question were easy. Then I was said to meet with senior manager for 10 mins for discussion and all went well. HR asked me to submit all my documents and I was pretty much assure, to receive an offer from the company. Now as days passes, there was change in hiring process for me and I was called and informed that there will be one telephonic round, which I passed. Then I was again called in office for some case study round. This whole process was now took almost 1 month, in end of week of march, I was informed that I am being selected for tech-lead but after that HR did not contacted me and even on follow-up my phone was not picked up.
