How to go to interviews?

Question

Career in IT

Recently I came to the company for an interview, passed the first stage, received a task, I am going to do it just to test my abilities, in case of failure, find out what skills are still missing and just to gain experience.
How much is it right to do this and how is it more correct to refuse in case of successful completion of the task and receiving an offer?
Considering the fact that (everything happens in life) I may want to return to this vacancy in the future.

Answer 1

Personally, I don't see anything wrong with that. Walk, train, communicate with people. It's okay to turn down an offer for any personal reason. You don't even have to give these reasons.
For example, the last time I was interviewing, I turned down one of the offers simply because in the end I realized that I did not like the country in which I would work. It was a large company that offered excellent salaries. I passed five interviews (including a home test), including onsight. When I announced my decision, the guys said "ok, not a problem, write to us if you change your mind."

How right is it to do so?

Morality is a loose concept. It seems to be tempting to say that “there is no way to divide”, but on the other hand, without going to several interviews like that, you won’t get an understanding of who you are in the market, what they generally want from you and what they can give. There is hardly a single correct answer to this question. There seems to be a conflict of interests between employers and employees.
In my experience, if you break up with the employer calmly, before completing any paperwork, then after a while it is quite possible to meet again. I have several companies with which we cross paths about once a year, do not fit each other and keep in touch for the future. The main thing here is the presence of mutual respect. All sorts of incidents happen in life and you can refuse for a thousand reasons. And asking to point out your mistakes, as well as providing your feedback, is not a bad idea. Especially if the person interviewing you was adequate. I even had such that the young owner of a small company thanked for the feedback provided and the exchange of experience in the process of communication. Until this incident, I thought that this did not happen at all, and he restored my faith in humanity. So see for yourself, no one will scold you for anything.
PS: And as for the "homework assignments" in the comments, they are right, they are often handed out in batches and the probability of a positive outcome tends to zero.

Answer 3

You reflect too much, gentlemen midshipmen.
Until you sign a contract or give your word, you are free to change your mind at any time for such a fundamental reason as “just overwanted” or “personal circumstances have changed”
This is a game, this is life, this is garbage, do not attach great importance to it, otherwise there is a danger of making money such dangerous and hard-to-remove crap as “fear of success” (suddenly it works out, I have to agree, but what if I don’t like it - I’d rather stay in the house and I won’t even try)
Good luck.

Well, you can try it a couple of times.
But in the vast majority of cases, the feedback will be too weak. Most often, "you fit" and "" ...
And to conduct only successful experiments is unscientific, you lose a lot of time.
In addition, in a company they can remember you and refuse you next time so as not to bother once again, and in large companies they can remember, also blacklist (this happens among HRs of different companies) if you abuse it a lot.
