Shopify Engineering Program Manager interview questions

Typical process of HR contact followed by panel interview with peers/ hiring manager. During panel interview immediately HR person seemed not interested in me, asked couple standard questions. Hiring manager seemed energetic and felt had a good conversation. Despite having all qualifications that was confirmed they are looking for got a canned response about not moving forward. Maybe I didn't fit their cultural fit but with company's reputation expected to at least a fair feedback rather than canned response. Oh well!
