Questions d'entretien chez All Risks

Typical interview process-started off with a phone interview with HR, then an in person interview was set up with 2 of the managers, all of which went very well. Two more interviews were set up and those both went well. Then a week went by and i heard nothing, another week went by and i emailed the HR person, I did not get a response so I emailed again and again no response. Finally she reached out saying no thank you....very long process and not very professional with HR getting back to you in a timely manner. Then about 6 months later I got an message asking if I was interested in another position, at that point I wasn't ready to go through 4+ more interviews especially after going through the first process which took forever!
