    Hi Jay. I am a corporate data scientist retiring from my job later this year. I was wondering how to use my skills to generate some extra beer money in retirement. You've given me some great ideas - thanks very much!

    2:45 To reduce Overfitting, we need to reduce the model complexity rather than increasing it. Your figure suggest to increase the complexity.

    1) for your IQ Coder & Premium pkg, for the practice questions, do you provide the answers or do you just hint at what's wrong? 2) what is the frequency & how many 1:1 sessions are offered with the Mastery plan?

    Unfortunately, people don’t vote educated. They vote on their emotions and the media controls most of the emotions..

    Voter suppression = voter ID. I’m pressed every time I drive a car and need ID, if I drink, I would need going to the bars and clubs. I am also oppressed. Buying paint at Home Depot I am oppressed. The list can go on, but I think you get the point..

    LOL, this guy is so bad. He certainly did not NAIL it. Out of the gate he asked a question that was clearly outlined in the IQ question itself. Then he proceeds to architect the system, by entity? Really? I would fail this guy instantly.

    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.

    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.

    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

    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).

As it is mentioned in the video that person who completed 10 projects in a week shouldn't be given more raise than a person who completes 5 project in a month. Ideally person completing 10 projects in leas time is more efficient and should be given more raise? Please suggest where I am wrong
