OOZOU Devops Engineer interview questions

Had an easy first round with HR, got take home assignment for deploying application using Terraform, completed assignment utilizing 1 working day and Saturday Sunday(weekend)submitted it on time, after a week wait when I heard nothing from them I sent them an email, than HR replied that " hey Usman we cant access your repo(github). I resent the request and waited for 1 weeks. When I heard nothing I wrote emails for update but got nothing, and after 1 week got an automated response that we are not moving forward with you, so I wrote for detail feedback, they sent me an email that your code has issues. Point is if I have spent my precious time for task they should arrange a cal for evaluation of code as they had mentioned on job add. Be a human please look at your reviews and learn something
