① Why is it said that recruiting people for blockchain positions is all based on deception

However, where are the opportunities for these innocent employees? To put it bluntly, some blockchain entrepreneurs only want to be "empty-handed" and exploit them layer by layer through "fooling". The use of asymmetric industry information has caused projects such as blockchain and digital currency to be over-packaged, giving people a feeling of "hope". The inherent "bad roots" of these blockchain entrepreneurs have, to a certain extent, led to the "sick" development trend of the industry.

Some blockchain entrepreneurs clamor to embrace the times, embrace changes, and embrace the future, emphasizing the charm of decentralized “fairness”. But in reality, it is done for personal gain and harms the interests of job seekers and other related groups. This in itself is a great injustice.

The asymmetry of information does not last forever. Blockchain, digital currency, etc. are all areas worthy of attention, but they cannot always be regarded as unlimited squandering capital by some entrepreneurs. For job seekers who want to join, they still need to keep their eyes open, otherwise they may be "surprised" if they are not careful.

② During the interview, what should you do if the interviewer deliberately makes things difficult for you?

For companies, the purpose of interviews is to recruit suitable people, except for certain circumstances. , many questions seem to be difficult, but they are actually testing the candidate's adaptability and flexibility. Therefore, you need to prepare some related similar questions before the interview, so that you can not panic on the spot.

1． "Brain teaser" questions

For example: Why are sewer manhole covers round?

Comments: Many job seekers feel that the interviewer has unclear intentions when asking "brain teaser" questions, and some even think that the interviewer is deliberately trying to embarrass people. The reason is that job seekers cannot prepare in advance for such questions. But we can see that, except for interviews for recruiting development and design positions, in fact, in most interviews, even if there are so-called brain-teaser questions, there are only a small number of them, and they mostly appear at the end of the interview. The interviewer does not ask for standard answers when asking these questions, but only intends to test the applicant's knowledge reserve, logical thinking ability and psychological endurance. Therefore, instead of complaining, job seekers should accumulate and practice more in these aspects and show full confidence during interviews.

2. Personal connections at work

Comment: If the applicant is not from the local area, but the interviewer needs to know who he knows locally by filling in a report or asking questions, etc., he probably wants to know from a side perspective. its stability. In addition, any position that requires external work now requires job seekers to have certain network resources, such as sales, marketing, reporters and editors, and even finance, accounting, etc. When the job seeker understands the purpose of the interviewer asking this question, he will not feel uncomfortable for no reason.

3. Ask "Do you have any questions to ask?"

Comments: A previous survey by 51job showed that more than 97% ofThe interviewer will ask the above questions at the end of the interview. Many job seekers know that the interviewer will have a "last question", but they are often speechless on the spot or worry about making a mistake afterwards. In fact, just as the teacher asks students if they have any questions at the end of a class, the interviewer's "last question" is mainly to examine the candidate's preparation before the interview and the degree of concentration during the interview. After all, some questions may arise during the interview. Things that will not be actively mentioned by the interviewer but are very important, such as holidays, salary, promotion, etc. As for what to ask and how to ask the "last question", candidates can know a thing or two from the previous interview process, but it is not very likely to rely on the "last question" to turn things around.

4． Advantages, Disadvantages, Personality and Temper

Comments: Regarding the issues of advantages, disadvantages, personality and temper, the advice to job seekers is: stay relatively honest. After all, the interview is a game process, and being glib and clueless is not advisable. As for the interviewer, it is of course important to examine a person's attitude and accomplishments, but it is not realistic to rely on a 30-minute interview to identify a person's strengths, weaknesses, personality and temperament. Instead of questioning candidates in order to lower their salary, it is better to consider how to maximize the value of a potential employee and avoid weaknesses to truly save costs for the company.

5． Personal finance-related matters such as income and expenses

Comment: As an interviewer, it is necessary to understand the income of the applicant's previous job, but it is a bit too much to care too much about other personal income and personal expenses. Some job seekers will deliberately lower their salary because they are worried that the interviewer will want to know too much about their personal income. However, everything has two sides. Job seekers can actually express a positive side to the interviewer: for example, even though their salary in their last job was low , but it does not mean that you have poor abilities. You are fully qualified for a new job with a higher salary; for example, a large personal expense is what drives you to work hard. You are willing to work hard in your new job and believe that you can rely on your personal abilities. Get more income. I believe that no interviewer cannot understand and accept a job seeker's reasonable explanation.

6． Regarding previous work experience

Comment: Work experience and experience are a very important part of the interview. As a job seeker, you should answer carefully and skillfully, so as not to reveal the secrets of the previous company, and to be able to To demonstrate your work ability, you must also prevent the interviewer from maliciously "borrowing your brain." For some of the interviewer's questions that may appear to be "borrowing brains", the job seeker can first respond generally with vague language. If the interviewer repeatedly asks for details, the job seeker can ask the interviewer appropriate questions instead of just pandering to them. In addition, netizens reported that some interviewers like to ask applicants to compare their previous and previous jobs. This is actually the interviewer's way of examining the netizen's job-hunting motivation and awareness of the new job. At this point, candidates don’t need to stick to the past—and avoid the embarrassment mentioned above—but should focus more on new jobs in the future.

ObjectiveGenerally speaking, the above problems are not too "excessive" in themselves, but we have to deny that there are negative situations in the market where some interviewers have substandard business skills, some companies have biased employment concepts, etc., which will affect the reputation of the entire industry. . Therefore, while we encourage job seekers to take any interview seriously, we also call on our companies to pay enough attention to any employee when recruiting, even if it is a hierarchical level.
