When looking for a job, the major is not right. I don't know if I can do it. What should I tell the recruiter?

When looking for a job, you'd better find a professional counterpart, so that you will do it much easier and won't waste your hard work and study these years.

If the job you are looking for is not suitable, then you should first ask yourself why you are looking for this job, because of your hobby or because you have no choice but to find a good job you like temporarily. If it is the former, it is easy to say. You can say that you really love this industry, and you plan to develop in this industry for a long time in the future. As for my ability, I will study as soon as possible to make up for my own shortcomings, so that interviewers can generally pass. If it is the latter, you can say what the interviewer likes to hear, but I still suggest you try to find a job you like.
