Supr Daily Senior Software Engineer interview questions

Worst interview process I have seen in any company. Very long interviews. Total waste of time. August 2020. They took 3 rounds of interviews. 1st was 2 hours 2nd was 3.5 hours 3rd was 2.5 hours 4th HR round. Note: You need to qualify a round to proceed to the next. After these massive interviews, they gave no feedback. No communication from their end. I had to ping the HR every other day for any updates. After a month, their argument is that they interviewed me for Staff Engineer but I was selected for SSE. And their salary bracket doesn't fit my expectations. How on earth can you interview me for a position I didn't apply for? Such a lazy HR , totally unprofessional and unreasonable. They just wasted 8 to 10 hrs of my time and are doing the same with everyone. Don't waste your time here.
