Meraki interview questions

I was contacted for SWE role with Cisco Meraki Sydney a few years ago, however unexpectedly the application didn't even pass HR screen after a call with a lady HR, this is one of the most unfair and unprofessional recruiting experience I ever had. I'm senior candidate and have been with recognized tech companies before including Cisco, and now with a better employer and feel have to write it down. The lady asked me sth which clearly stated in my CV with tone appear to be biased and unprofessional, I answered all queries with patience and finished the call and later on got msg that it's rejected. it's the 1st time got rejected during HR screen, and doesn't make sense as the role JD fits well with my background/skillset and I doubt hiring manger ever looked at my application. Though it's an unpleasant experience, looking back I'm actually happy that it didn't go through as who wants to work for a company like this, it's a shame on the HR staff
