conclusion
The first is to feel that their foundation is not enough, big factories seem to like to ask these underlying principles.
Another part of the reason is that the information has not finished reading, on the one hand, with that information before the examination of the surprise make up for a few days can also easily cope with (here still want to thank the information, really cattle), so I feel good, the information is not how to go on.
My previous preparation only involved Java, Android, computing network, data structure and algorithm, which was not enough for the interviewers to investigate other basic courses.
Next or should check a leak to fill a vacancy, undertake targeted review.
Finally finally, that set of data this time must see all, is really too comprehensive, each knowledge point has covered, almost I interview all the knowledge point of the problem have inside! Here is also free to share with you, I hope you don’t make the same mistake as me!! Make sure you finish it!
