Send CV and get a phone call after few days. I went to its company in Shanghai. First I did some exercise about C++ and database. But I didn't prepare very well so lots of problems I couldn't solve. The interviewer evaluated the test and felt disappointed. I should use some tools or materials to prepare.

i was called for interview since i was the winner of the cloud 20 20 competition done by Unisys. firstly i finished my intern without any interview but after completing i was interviewed and there i was asked for the basics of OS and Programming Skills
