Turvo Software Development Engineer interview questions

Hr contacted me over the call. They have postponed my first 1, and second round each by 1 week. Due to this my interview prosser went over 1month. During the 3rd round we have faced some technical issues and couldn't take it forward. Interviewer has requested for rescheduling of the interview. Hr didn't respond over rescheduling of the interview. No response from the Hr for calls and mails. Now it's clear why they have so many negative reviews on Glassdoor .
