Ziosk Software Engineer interview questions

Went through the online coding test. First they said they were very impressed with my result. The HR guy fixed a date for personal interview. Then after a day he called me and said that I did not qualify the test and they will never consider me as their candidate in future. No reason was given. I recently went to a restaurant that used their product. It looked so cheap after I swiped my card the bottom came off and the paper roll used to print the receipt fell off. I then read some employee reviews and so glad that I did not get sucked into this company. It looks like they pay less and employees are overworked.
