one round of interview related japanese level and speaking level in japanese, basic technical round questions and managerial round, one round of interview related japanese level and speaking level in japanese, basic technical round questions and managerial round

I applied for their chennai location.The first step was a telephonic call where the person asked me lots of technical questions related to Java.The questions were easy if you are clear with the basics.Also he tested me for the Japanese level. I cleared that round .After that they send me to their Noida location for my japanese test where I received a telephonic call from chennai office for my japanese test. I also cleared that. Now the HR asked me for my salary slips. After providing those slips she told me that I will be receiving the offer letter by next week. One week passed no update. After two weeks I tried calling and contacting HR but to no avail. After a bunch of emails and 3 weeks later I got an email from the HR that we are no longer looking for the position. The HR and management kept me hanging for around a month assuring me that I will receive an offer letter. I don't know why these employees are burying the reputation of a japanese firm.
