Jio Web Application Developer interview questions

i applied through linkedin .1st round was a technical interview and interviewer asked basic questions about javascript, html, mysql . based on my resume . Interviewer was very friendly and the interview went well. Everything went well i submitted the documents they asked and gave PI assessment . Then they asked me to wait 10-15 days i waited patiently . After the given timeline i called hr for follow up she ignored my calls and my follow up emails . One day she picked my call and said that they are giving preference to freshers and not experienced candidates.. They wasted 1.5 month of my time. I expect ,if they had planned to put my candidature on hold ,they could have told me or dropped a email for that . Very unprofessional behavior by such a reputed organization.
