Advanced Wireless Technology Group Network Architect interview questions

Interviewed in November and informed one more stage to go ahead, had another interview month and half after (mid December), then informed that hiring process has 5 different interview stages, kept asking for updates and receiving updates that "waiting for managers feedback or to get back with dates" this was going on until February, at this point I quit chasing and chose I would not want a job even if I was offered one as the company and management seems unreliable already before I even get there.
