Descartes Systems Senior DevOps Engineer interview questions

1 screening call for about 15 minutes followed by a short video interview with one of the team not sure if he was manager or not , it was for about 20 minutes, I answered all questions right and it was for me junior level questions I was expecting them to be more advanced , despite that and after they stayed 3 weeks with no feedback , they came back asking if I got new position yet or not I said I am in final stage interview with another company then they took more couple of days and come with feedback saying "you are missing some technologies required" which was completely not true , if I missed some technologies they would not take all this long time to come back and I am sure I answered all technical questions right , they were very easy and looks like junior type ones
