Look face questions
normal first step will certainly face questions see, I am no exception, in the process of looking, I found some articles written in good, helped me a little not recommended, as follows:
the Java interview questions Complete Works (on) a lot of basic things, recommended to walk.
Major companies to develop interview questions Java back-end summary of
the interview experience and summary --BAT, Netease, mushroom Street
on Java interview, you should prepare these knowledge
-depth study
in the process of looking face questions, you will encounter some of their no contact or not previously studied in depth knowledge of, for example, the most frequently asked internal HashMap implementation principle, which prompted you have to begin to see the jdk source code or learning something new. Look at the source code is a very important step, it is difficult to start, but will make you a lot of benefits, see the source code of the process if you encounter a place can not understand, Baidu can look at other people's understanding. I study the source code, a few people read the articles written about the source of very good, as follows:
familiar with the project
to find since most of their work developed over Diao function, the function of the entire process involved a thorough grasp and stuff. The project is part of the interview will ask, and is usually a function point-based expansion to ask, so you must have a deep understanding of this function, there can be ambiguous place. If you have time, can relate to knowledge also get to know the best.
Do face questions
many companies are interviewing, if you're not ready before, it is easy to place in a variety of small mistakes, it is recommended to go to some sites do more topics face questions, with my own cattle off network.
Learning record
the time of day and learn their own learning content is recorded, you can make yourself more motivated to learn, learning is a tedious process, you have to keep yourself motivated.
Resume, the interview process about
which sites to cast?
Pull hook net, BOSS straight recruits, headhunting network.
Whether the sea to vote?
Cast your resume is divided into two cases.
1) no club recruit interview experience: recommended HAITOU way, as long as the job requirements match can compare with their own vote, a total of interview experience. This link can be increased two to vote resume website: chi and worry-free.
2) since that agency recruit interview experience was enough: put those job matching, satisfaction with the company's position. The company can go spotted evaluation network, Baidu, know almost other inquiries.
One day about several interview appropriate?
The ideal situation for the two interviews, usually in the morning around 10:00, usually around 2:00 pm. The company suggested that the ideal place in the afternoon, because more adequate afternoon, allows the company to more fully understand you. When I started to surface, every time a bad morning, good afternoon plane surface.
Often did not vote resume later?
I had never thought this resume screening off so hard, I might actually resume the few bright spots, HR Furthermore many are not insiders, so they see the most direct is on your company and your family to graduate school If you're not out of the fast hardware company / school, and I may run into the same situation, coping way it is to vote.
Whether the Naked resignation?
I started to work side edge vote, and then use the days off the time, or leave to go to the interview. Later, more and more interview opportunities, leave too frequent, embarrassed himself, and he is already confident enough, this time I chose to bare speech. Naked resignation Another reason is that you will find in the interview process, some companies dignitaries to be tight, if your resignation process is too long may cause you to miss this company.
Note
1) day before the interview time and the route considered good, better not be late.
2) back a bag, with a good resume charging Po, paper towels, umbrellas.
The interview process
Written common problem?
Common interview questions interview questions above are linked to the basic. I only mention a few: 1) to write SQL: SQL write very often study group by, the inner and outer joins. 2) handwritten code: hand-written code is generally a single test cases, sorting, threads, consumer producers. I suggest that in addition to sorting algorithm bubble sort, but also the best handwriting one other sort of code. Just think: If the interviewer are generally written in bubble sort, and you write a quick-sort / heap sort, be sure to give the interviewer to leave a good impression.
