Hitachi Senior Software Developer interview questions

HR called up after reviewing my LinkedIn profile. Discussed about salary and job requirement. HR said there is only one technical round for 1 hour after which decision will be made. Ended up giving 3 technical rounds with 3 different individuals for 3 weeks each one saying interview cleared. Supposed to be last interview with Manager who also gave positive feedback after interview. HR calls to say you are selected but cannot give job offer since we have to interview another candidate for senior role first. From my experience they don't care much about other people time or efforts spend in this interview process. Entire interview process and job listing looked fake to me since after each interview I received positive feedback yet NO job was offered. STAY AWAY!

I applied the job on line. Then got an invitation for on-site interview. Interviewed with the development director. He gave professional feedback immediately at the end of the interview - very helpful.
