Ricoh Software Role interview questions

Horrible interview experience with RICOH innovations, Bengaluru Initially the technical interview ( with 2/3 rounds) went on for 2 months. Later, the HR informed that i was shortlisted for the role. then salary negotiations happened and they sent a salary break up in excel sheet. the HR also informed that they will send the offer letter next day. Suddenly, the next day i get an email saying that the position is closed because of changed business plans. I was shocked and dumbfounded to see the response from the same HR.
