Trimble Software Engineer interview questions

My interview was scheduled at 10. The first round of interview went about 2.30 hours. I was selected to the next round., which is manager round. I had cleared that one too. I went to Hr discussion. After completing all these they told that we will send you an offer letter within EOD. That's the final time I had a conversation with them. It was close to EOD, so I started calling them. They didn't pick my phone. I mailed them still no response. I called both HR and I got no response. I say this is this the worst response I have ever received. I thought I deserve to know what is the final decision. Since there was no response from them I am happy I didn't pick this organization. Even before joining if I am getting these kinds of response I thought if I had joined then I would have ruined my career. You should have manners to call the candidate to tell what their final decision. I spent my whole day for an interview and you guys are like we don't care. I can see that this ideology of irritating candidates will go no good to your organization. I also got an offer from a better organization at a much higher package. So don't think I posting this because I didn't get offer your worst organization. Learn some manners in your thrash organization,
