OANDA Partner Software Developer interview questions

I received a phone call after a week of applying for the role. The interview was with a senior HR recruiter. The questions were simple soft questions about myself, my background, and my cultural fit with the company. At the end of the call, the rep told me that she would like to schedule the next round with the technical team, an asked for my availability. After I submitted my times, I heard nothing back for a week. I was given some excuse about her being sick. She then promised to get back to me in a few days. Again, I hear nothing. After the 3rd week, I ask again about the progress of my application. I then get told that they went with someone else without any apology. I was also a customer of theirs. I have now moved my business to their competitor. I will never work for this company, and I am telling everyone I know to stay away from them.
