POS360 Senior Project Manager interview questions

Applied in mid May. First interview was a zoom screen with a fellow PM. It went well and I was given word that they're very slow in their hiring process and that it may take a few weeks for them to work through everything. I gave an Ok and proceeded to wait another 3 weeks before I was invited to come to their office. Met in person one of the founders who was late to start (not a problem). It otherwise was an Ok interview with plenty of accolades to my experience. Was told again things will be slow and I'll hear back in a few weeks. I followed up twice as to next steps and was ultimately ghosted.
