Canonical SRE DevOps Engineer interview questions

Do not waste your time with Canonical. Their recruiter contacted me and told me that there is a good opportunity. And then asked me to send resume to them and also answered some questions about my experience via writing. I think based on the questions they asked ,I’m a good candidate. At the same night I checked the glassdoor and found that all interviews are negative... And then after a week end, got the the email from them. “We are writing to let you know that we will not progress your application further.”. Ah ha, no phone call, no interview, no feedback, that’s it. I think they just wasting candidates and recruiters’ time.
