i applied for both positions ( A220and EMB195)
going through the 195 FO selection process , it took 6 days for me to get a live interview (scheduled next week) from 4 recorded questions interview last week .
I have 9000+ with 3750 PIC on E175 .
I believe they would lower the requirement as they might run dry on type rated PIC guys/ gals as there is lot of hiring going on on other airlines .
