ABB Senior Process Engineer interview questions

Tech Interview by UK Manager, HR interview by Banglore HR. HR promised for travel reimbursement and requested me to travel from Hyderabad to Bangalore for interview. After interview, I found it is different from my current job. I rejected offer. HR did not pay my travel reimbursement. They smartly told me, they will send reimbursement form later. they sent to my mail after good followup. I couriered all my original bills to HR. Called after 2 weeks for followup. they told they have not received any courier. Then I sent scanned copies ( soft form). they played a drama that some head office has to approve. and always there is delay because of one pending signature. After 7 months follow up, I gave up the idea of asking them for reimbursement. Guys dont trust ABB persons. they will cheat. Dont believe their future promise
