Cognizant Technology Solutions — I got an email to attend managerial round after completing hacker rank test but no any invite link or any update

Address:

Hyderabad

I got an email for job opening as a java developer 2-5 years experience from cognizant employee.

After replying all my details, i have received an email to attend hacker rank test and i have attended and did well. Next day i received another email from same person confirming that i have passed the hacker rank test and asked me to choose a time slot for managerial round on friday and i have choosed and replied back. As it was friday[protected] i have taken a leave to attend this round of interview but i didn't received any interview link or any details. I have mailed again to the same person but no responce.

My question is why to simply waste my time, i postponed many works on the same date and took an emergency leave in my current company to attend this interview.
