DND Software Engineer interview questions

It was a face to face interview near airport, need to provide NRIC and name to get pass the Airport Police office. It was a 2.5h trip from where I live, but I agreed to the physical interview and provided my information to the HR accordingly. On the actual day of the interview, I reached at the Airport Police 30min early, estimating the time needed for them to process anything, unexpected to hear from the Airport Police that they did not receive any of my particulars. As such, I messaged the HR politely to check whether my information has been faxed over from their side, and called the HR 3-5 times, but the HR neither pick up nor come online. I went online to search for the company's official number and called, but no one pick up as well. The Airport Police also provided me with the phone number registered by the company at their side, but it was a wrong number. As such, I waited for 30+min until the interview time passed, and the HR still does not pick up my call, hence having no choice, I left the HR a message before leaving the Airport police office. 3 minutes after I sent the text, the HR came online, and still said nothing. 2 days after the scheduled interview, the HR messaged me again, asking me to go for a physical interview, as if nothing happened earlier. TLDR: I made a six hour trip to the other side of Singapore for a scheduled interview, and got ghosted with no apologies.
