$/Users/sudhakar/go/bin/dlv core ./hello /cores/hello-72335-20200427T185443Z 
unrecognized core format

Answer 1

At the time of this post darwin/amd64 is not supported by delve.

Ref: https://github.com/go-delve/delve/blob/master/Documentation/usage/dlv_core.md

However this can change over time (delve may add support to this arch) attaching screenshot of documentation (at the time of this post)

Special thanks to delve-dev list member (Choudhary Sourya Vastayan) who pointed me to this.
