Ali HR Interview:
1. Why did you leave your last job?
How do you see your career in the future? (including the distribution of work and family, how to balance the relationship between family and work, overtime, considerations when choosing a company, location, etc.)
3, salary expectations (do not directly say the number, must not show how much money or what level I do not go, this is a taste problem rather than ability problem)
Some questions candidates have been asked:
1. What was the biggest challenge during the project? How did it work out?
2. Why did you choose Ali?
3. What is the most fulfilling thing?
4. What do you think are the weaknesses/strengths of your job?
5. What are your strengths and weaknesses in your character?
What kind of person are you in the eyes of your friends and relatives?
7. How do you feel about working overtime (can you accept 996, 997, 007)? I think we have to work hard to realize our dreams, so I am prepared and willing to fight with my friends. I can work overtime, and my overtime intensity is quite high now. Because I love it and I want to do it well. 8
8. Can I accept a salary cut? If the candidate’s tonality matches (officially enough), you can say something like: I also understand the ant gold currently salary structure, I believe that the company will give a reasonable salary according to my abilities, I believe that as long as you get things done, it will be some for ants, such departments, “we are creating history, we’re doing a no one has ever done, so it must be difficult, affirmation is to pay a lot of effort”. Interviewers will especially appreciate this.
Interview Tips:
1. The status of the interview is very important: For two examples, a candidate who was offered a job last month with non-Internet background and non-front-line company showed strong interest in Ali during the interview, and HR mentioned it to us afterwards and was very impressed by this candidate. Another candidate who just died today won both rounds of technology at one stroke, and finally the HR failed. HR gave us feedback that the candidate just quit his startup company and seemed to be depressed and have no idea about himself. To sum up, the interview should not be too submissive, passive, nor exaggerated, but to show your respect and fight for a good opportunity, let the interviewer feel that you are interested in them and the position.
2, answer the question: feel the answer out of the other party will not like, you can do so: relevant answer questions, pay attention to emphasize their own ideas, to let the interviewer can empathy, such as shenzhen housing price can attract empathy, e-commerce related platform, stable, there is room for rise, etc.
Matters needing attention:
1, Ali inside HR is to understand the business, will combine the judgment of candidates and business control screening, do not fool them, is how should…….
Ali is more important than most companies feelings and dreams
Ali’s mantra: Optimistic, smart, honest, introspective
