    The problem with this is that there is no person who can’t legitimately vote if they want to. Voter suppression is a myth. There is no law or voter rule that makes the circumstances around voting identical for everyone. Just because I live further from the polling place than someone who could walk there does not mean my vote is being suppressed. Suppression means I am not able to vote because of some law. That does not exist in this country.

  • @victoruong1677
    @victoruong1677 10 дней назад

    Clarifying questions are a must for product type interviews, but Eshan asked wayyyy too many. I think a better way is to list out potential factors and then ask the interviewer to narrow down which issue it could be.

    Is this about how an ML design interview SHOULD NOT be conducted? The interviewee talks like a professor with his snide "right?" comments every now and then. Could also help if you took 2 extra seconds and chose a proper drawing software rather than make a gibberish puke of scribbles all over. And possibly slow down your speed to go over system components rather than stuff like HRNN etc.

  • @harmanbaidwan1713
    @harmanbaidwan1713 16 дней назад

    No, this is def wrong. “Entry” level implies straight out of an undergraduate degree or straight out of a practical internship. The average you can realistically expect is like 78k - 90k. Those six figure jobs straight out of universities are usually FANG companies and you have to be the top 5% in data science to get that. This guy is talking more about intermediate to senior level positions

    @soumyajitganguly2593 18 дней назад

    LOL this is an easy problem! The fact that you can jumble up all the letters to form your palindrome makes this quite easy. If you want a good challenge: try solving the same problem where you cannot jumble up the letters (longest palindromic substring).

Ideally person completing 10 projects in leas time is more efficient and should be given more raise? Please suggest where I am wrong

    You wan a system that overfits and hits lots of false positives, as false negatives can be catastrophic, legally, for the reputation of the business, could even lead to regulatory action and media scrutiny, killing sales, market cap, etc.. You then have agents go through the false positives and efficiently decide if they are truly false positive or not. This data can also help train the model. The cost of hiring people to go through and check is much lower than losing 5% of market cap due to negative press.
