So to summarize, with some stats from searching on Indeed with the title and country set to the United States. I checked the first page of each if they had the correct roles posted. Core data roles: 1. Data Analyst - 22,375 jobs 2. Machine Learning Engineer - 15,644 jobs 3. Data Engineer - 7,655 jobs 4. DBA - 3,664 jobs 5. Database Developer - ? (searching "SQL Developer" listed 1,923 jobs.) Dying roles: 1. Data Scientist - 10,919 jobs 2. ETL Developer - 5,449 jobs 3. BI Professional - ? (searching "Business Intelligence" and "BI Developer" listed 5,928 jobs and 5,494 jobs respectively.) Note: ? is because too many irrelevant results were coming up when searching for the role on the first page itself. So I wrote in parentheses what I think is the closest alternative, which returned much more accurate results. BTW In the new Google certificate, BI Analysts and BI Engineers are presented as the two main BI roles, not sure if this reflects reality or not. I didn't provide stats for these either due to the same issue of irrelevant postings when searching for their title.

Great video! I have been religiously following your advice. I wish I could say I was part of the subset of people who complete your courses and go on to get a Data Analyst role but my current (new) IT support job has taken priority in the last few weeks. Can't wait until I free up the hours needed to get properly stuck into your material Mike! So helpful for people like myself who aspire to become very competent in the area of Data Analysis and make an impact in that sphere. Thank you so much for putting these vids out there. It really helps "dunning kruger kids" (like what I used to be, now in recovery from that idiocy) sort out their worldview when it comes to the data space. Good job!

Well I am a Da Engineer, who never worked as DBA. I was a an overskilled technical support and then switched to a Data Engineer type of job in on-premise ecosystem. It was a hard switch and hard to get the job in the first place but I managed. I had also advantage of advanced german language, which definitely helped me then (and still does)

I enjoy the direct nature of your videos (I've binge watched many) and although I mostly agree with you, I do feel that you somewhat oversell SQL and neglect to talk about the importance of software engineering fundamentals for DE/ML roles. What's your opinion that data engineering will start to split into two different "roles" in the future: Analytics engineer (Heavy SQL, data warehousing, close to business, etc.) and Big Data Engineering (Heavy programming, dev-ops, kafka, spark, further from business etc.). I've been a DE for the past two years and, outside of DDL statements, haven't put much SQL into production. IMO the most rewarding elements of DE is this dev-ops/ micro-services work, so I am curious to hear your opinions on this topic. Thanks!

2:08 - (When talking about Machine Learning Engineers) ...they build the models 3:50 - Machine Learning engineers ... don't code their own models What is the difference between 'creating' models and 'building' models, in this case?
@thedatajanitor9537
@thedatajanitor9537 Год назад
Creating a model means writing all the code for the model. Here, I wrote this simple linear regression model from scratch. qr.ae/pvbaH7 When we build model we use libraries and frameworks like TensorFlow and PyTorch for deep learning and XGBoost for traditional modeling. These are already written. We simply pass the data into the model and it provides us with a prediction.

Hi Mike. Do you think job titles matter? For example, what if someone does the job of a Data Analyst but their title is BI Analyst. Is that going to matter when applying for any future roles?
@thedatajanitor9537
@thedatajanitor9537 Год назад
Hell yes it will. If you're a data analyst and you're interviewing for a BI role and can't define how a decision tree works the interview is over and you just lost that job. If you're a data analyst and have never done any data mining how in the hell are you going to answer the data mining algorithm questions in the tech interview? At real companies titles matter.

I am in the process of becoming a DA. What is your take on a the WGU BS Data Management & Data Analytics degree? I'm encouraged by your advice that all DA's do is make dashboards and KPI's and after my move to Washington, I'll use LogikBot, but many roles require a bachelors degree. Would you recommend the WGU degree as a supplement to your courses? I am in a position to where I am not in a hurry to get a DA role and would like to get the BS (double entendre intended) out of the way
@thedatajanitor9537
@thedatajanitor9537 Год назад
All data analytics degrees are a waste of time. No real-world skills are taught in college. Focus on SQL and a tool like PowerBI. Now, you *do need a degree* but no one really cares what that degree is in and comp sci degrees don't give you any extra credit on your resume. Companies want skilled candidate with the tech they are using.

@thedatajanitor9537
@thedatajanitor9537 Год назад
The only role you should be taking is the data analyst role. It's simple. You take the Transact-SQL course and fill in the interview preparation. Then you study that guide until you know every SQL question on it. Next, you take the data analyst course. You learn as much about PowerBI as you can. You then study for PL-300 using my exam simulator. You then sign up and try to pass the exam. That's it.

Would majoring in Statistics & Data Science at UT Austin limit my career beyond a data analyst greatly? It works better for me logistically than majoring in Computer Science but I'm afraid it won't be as useful. On the other hand, it seems like the computer science major would make me spend a lot of time learning stuff I'm not super interested in like computer architecture, coding in C, etc. I initially was drawn to Data engineering but now I'm considering data analyst and eventually moving into BI. What do you think? Would getting a masters in Computer Science after also help?
@thedatajanitor9537
@thedatajanitor9537 Год назад
You need to watch my videos Colby. BI is dead. It's been replaced with machine learning. You have three top tier options in the data space. The DBA, the data engineer and the machine learning engineer. The data analyst is not considered or treated in the industry as a top role.

@thedatajanitor9537
@thedatajanitor9537 Год назад
No such thing as an NLP analyst. There are machine learning engineers that specialize in NLP and deep learning. They are still called machine learning engineers and while cleaning data is a little different, they still spend most of their time cleaning data. All of these models are called "generative" Ai models and they are all deep learning. These roles are insanely hard to come by and most of them are hardcore programmers.

@eddyateye810 Год назад
You addressed it to Mike, however here's my take. If your undergrad is in tech...hurray, you get to learn a lot, databases, programming, etc. If you put in some good effort plus summer internship, you should be skilled with the required sql for entry level job. Then you do tableau or power bi. If your undergrad is not tech related, you can get started with databases, either self learning or buy a good course. You should have some programming skills if your end goal is mle. If you plan your education well, you should be marketable right after sch.
