They asked to make some Angular app which can scan products and add them to cart. The interview process is very simple CTO call to know about projects and problems solved, then call with Nikil who is in the UK for some very simple Javascript problems. But after I submitted the test they got mad that i referred some code from internet. How will someone know barcode scanning implementation without referring to some examples over the internet? Very bad interview experience.
