I received an email said the position was closed but I still got a phone call said they would like me to come do a test and prepare for future recruitment. I went to take this visual accuracy and speed test. Several pairs of numbers were given in the test and there might or might not have small differences in each pair. And what you need to do is choose “yes” when they are difference and choose “no” when they are not. You will have 7 mins to finish it. It was easy for me. And I passed the test, I was told I got an interview the next day. HR manager were very nice. She asked me several behavior questions and told me they would review it and keep in for record, and contact me if there are any opening positions fit me.
