Loblaw Digital Process Engineer interview questions

I was contacted by HR and then had 2 rounds of interviewing; first with the hiring manager, and next was a series of back to back with 3 senior executives. The interviews themselves were done well and professionally. The trouble though is with the HR process. For each of the interviews, I was contacted over phone and asked to provide availabilities. The HR person then replies saying a certain date might work and will confirm. Except the confirmation never happens. You wait a few days and then mail them,no replies. Now call several times before they say another date might work, then the process repeats. You anxiously wait hoping they will confirm the date except they always forget. Like I said my interview went well, after the second and final round they promised to get back to me in a few weeks. Except I didn't hear a word till date. Last I heard they have new HR personell, so things will hopefully change.
