This doesn't really answer the persons question in my opinion. Are we supposed to assume this person has a BS in Computer Science? In that case it's more like 4.5 years and not 6 months.
I don't think anyone can give a definite yes or no response here. There are lots of factors that contribute to one's successful job interview which then translates to a job offer. I've read many blog posts and ex-Googlers say that practicing leetcode problems increases your probability of making it through the technical rounds. An applicant also needs to have well-rounded knowledge of general CS fundamentals. So I think the answer the OP is looking for is maybe: try to practice data structures, algorithms and get the fundamentals right specific to whatever job title they're applying to, and hope your interview goes well.
