    I have been seeking for an efficient money-making method and luckily, I found out about “Sοdαmzοt Sizo” (Google it) from my good friends. After having a go, I grew to become a daily earner more than a hundred dollars. You need to try it for yourself. .

    You sir, are absolutely correct! This is how we can tell the difference between someone that knows what they are doing in Data Science vs. someone that doesn't. If the first thing out of your mouth is Deep Learning or Machine Learning, and you can't talk about improving the business, you are NOT getting the job PERIOD.

    for a commerce guy who is not an engineer……….all this doesnt make sense……how difficult is it to run business and make profits and not bother about squezzing every single ounce of productivity, by making life more complicated , just to create jobs for engineers ? but i guess profits are just that mouth watering, is it ?

    You are too good. What is your take on Blockchain? Any videos that you could make? I am interested with your take on Blockchain and how to go about programming for Blockchain. Recently, I took part of a Blockchain session and was amazed with the use cases that it could apply to. Thanks.

    You are working as statistician bro or data analisys..,.. when statistics, businnes analitycs, data mining and then machine learning are combine… there are suddenly a lot of stuff related to data so then data become a science itself thats why one can talk about data scientist and data science…. companies look for "data scientist" because they thing they are gonna solve all the problems… managers feel better so than with a statistician….

    Hey Joma Tech guy! So whats the educational journey for someone who wants to reach the top of those large company hierarchy pyramids? I mean, what degree/masters/phd route should one follow to be applicable for those jobs? And how long are those? I'm 32. Could I be in the industry before 40?

    Hi Joma, I just took on a new role where I'll be working directly with companies that hire all these positions you mentioned. I found this video really helpful, however it moves a little too fast for a beginner like me. Would you be willing to send me a very basic (from the beginning) to end of the whole data science picture? Meaning, as if you were trying to explain to me what each role does, what they need to know in terms of programs, software, etc.. and how it all works together- and also what types of companies hire what roles.. I just need a basic understanding of how to help companies with great IT professionals, but need to understand the whole bigger picture, and exactly what they do including all the buzz words.. Thanks in advance for any help 🙂

    Hey Joma!
    I'm a high school grad going into compsci and I really don't know much about the different branches within both back end and front end dev. I have coding experience in java, js and python. What are maybe some small data science projects or projects that I can work on that would let me build skills for that career path. I really just want to dabble into every branch rn and hone in on one later.

    What about someone who has figured out human behavior and human nature, why we do the things we do? Why we avoid problems and why. I know how to assert yourself to your manager, hold them accountable, test your theories with in company policy and have data to support your ideas, if the change. Managers are suppose to support their employees and if you have. Reasonable request, document and have witness to your request, someone is more likely to do what they say when there is a witness, having a witness or being able to document your request, email is a great way to document your request. And set an expectation so that they are accountable to at least replying. If they ask you a question to distract you or dismiss you, ask them how or why and put the responsibility back on them to prove you wrong, especially if you are a benefit for the company. If you keep giving him good ideas and never document that the ideas are coming from you, they are probably getting all the credit, a real manager gives credit to the team they manage, they get right in there and work along side you. If they aren't, they probably sitting back and not really working. That's how you know the difference, they give credit where credit is due, if the team is not getting any and how see the manager rewarded then he probably is claiming to be the reason for success. Its greed and psychology, if a reward comes directly from him as yourself why? Did a promotion happen or bonus? Is the reward something cheap and our character? Then its probably a distraction. He's the middle man keeping the credit for themself. Know your chain of command and company policy, make allies and get friendly with others if their same rank so you can go to if you are suspicious. Observe their behavior and any deviations in that behavior should make you ask why? Track that behavior and see if same factors have same result, humans are creatures of comfort, what makes you change your routine? I know human behavior extremely well now and human nature and can mostly read everyone like a book and know that everyone will eventually get stuck when certain needs are met and stop learning and seeking to achieve more. You're probably wanting to make more money so you can get out of parents, roommates, small place, looking to make more money to get into better position to impress a prospective mate or impress parents. Then what? Is it about money? Or are you really trying to help the betterment of mankind? These are not meant to be offensive questions, as no tone of voice is implied, I am more or less asking questions to help you see I may know what I am talking about.

    Can we pursue other career and do the work of data scientist simultaneously ( as a part time ) ?

    First of all, thank you for the insightful explanation of what really is data science. It really helped me to organize my topsy-turvy knowledge on specific categories in data science hierarchy.
    Since Data Scientist is a dream job for me, I wanted to know what I should study in the 3 years of my high school. Also, I want to know which major, and which degrees I will need in University to become a Data Scientist.
    Thank you!!

    September 14, 2019 at 10:52 pm

    You are spot on about the low hanging fruit. I work for a medium size company and your explanation is exactly what I experience. And here I thought we were just lagging behind.
    80% of my job is cleaning data.
    One of the key problems I find in companies that I worked for is legacy systems. It's crazy how much time we spend just dealing with legacy systems.
    Would be interested if that effect you work.

    A random question a year later.

    I have a background in US Navy intelligence and we did much of the analytics side of things. Generating solutions to problems.

    Due to this I want to work in Data Science since it fulfills my desire for such analysis and dissemination of information. However no degree.

    To get such a job, how much more do I need than a run of the mill no experience college grad?
