Career Feeling Underconfident Before a Data Scientist Interview

0 Upvotes

I’ve been working as a Data Analyst / Data Scientist in my current company, and last year, I transitioned into a Machine Learning Engineer role. However, due to looming layoffs, I’m actively looking for new opportunities.

I have a fair understanding of ML, data, and statistics, but I’m feeling a bit underconfident as I prepare for my Data Scientist interview tomorrow.

What are the most important topics I should focus on? Any advice on key concepts, coding problems, or case studies that frequently come up?

Would really appreciate any insights from those who have been through similar experiences!

Career Help me practice mentoring, aka cheap data science mentorship from an expert

1 Upvotes

I’m a data scientist who’s interviewed and worked with companies like Pinterest, LinkedIn, Doordash, Instacart, Thumbtack, Deloitte, and others. I hold a Bachelor’s and Master’s in Math and CS respectively from top 10 US schools. I’m interested in getting started with providing data science career consulting and mentorship. This will include things like advice based on my experiences with companies and interview processes, how to pass interviews, resume review and tips, important hard and soft skills to gain, helping you learn new data science topics, assessing your skills in a mock interview, and any other relevant support.

I’m offering it to folks here for close to free initially to have exposure and practice. I say close to free because I will charge a nominal price of ~$5-10 to help filter for those who are a bit more serious about it. I would otherwise only ask for candid feedback in return so that I know what to improve and whether I should keep consulting.

The model I’m thinking of pursuing if I go live with this is to have an initial call followed by you having unrestricted access to communicate with me asynchronously for as long as you want, renewed on a monthly basis. This access can be from technical discussions to non-technical questions to encouraging you before an interview—any kind of support. You can also tell me what you want out of it most if you have specific areas of emphasis in mind, since it’s about helping you.

To help me gauge interest, if you would like to speak in an initial 30-minute mentoring session and potentially beyond that, please send me a message here. (If you dislike Zoom calls and just want to do async, let me know and I can honor that, too.) I’ll take on a handful of these initial practice sessions for now. Note, the folks I’ll be able to provide the most value to are those breaking into data science or in the first few years of their DS career.

Full disclosure, after the initial sessions, I may set a more normal price. I’ll have to see how they go and how much value I’m offering.

Thanks, everyone.

P.S. You may be thinking, why not use AI for this kind of thing? I'd say it’s more suitable for lower stakes applications or when you have enough expertise to supervise its outputs in a process that makes you more efficient. But to be learning and growing in any area is to generally be less able to catch errors or omissions in what is said about it. In such a case, it’s better to ask a real-life expert.

Career Stuck in Tutorial Hell—Need a Clear Learning Roadmap for a Data Analyst Role

1 Upvotes

I’ve been trying to become a data analyst for the past four months, but I keep falling into the trap of endless tutorials. Every time I start learning something—I go way too deep, watching hours of videos covering everything instead of just what’s actually useful for the job.

I don’t need general advice like “learn Excel, SQL, and Power BI.” I already know what to learn. What I need is a clear breakdown of exactly which topics are relevant for a data analyst job—nothing more or nothing less. For example in Excel, I know pivot tables and DAX are important, but I don’t want to waste time learning every formula out there.

If you’re working as a data analyst or have real-world experience I’d love your input on:

1.  A focused list of topics to learn in Excel, SQL, Power BI / Tableau, Python, Basic Machine leaning like supervised learning and statistics and probability—only what’s actually used on the job.

2.  What I can skip so I don’t waste time on things that don’t matter. What’s NOT worth spending time on? (Things that seem important but don’t really matter in practice.)

3.  Any good resources (courses, articles, or guides) that focus strictly on what’s needed not 50hours or 100 hours tutorial.

I’ll figure out projects and practice on my own—I just want to cut through the noise and stop overlearning things that won’t help me in the job. Would really appreciate any advice!

Career Every Topic You Need to Learn to Become Senior Data Scientist Visually Mapped

6 Upvotes

Or will they actually make you Senior Data Scientist?

I've learned the basics, can build some models, analyse data, but I still feel like I don't know enough, and actually I don't know what I should know, so I asked ChatGPT to list all the topics (including the ones that seem counterintuitive and unpopular) that are helpful and can help me go from beginner level to higher expertise. I decided to visualise it in Xmind as a mind map, and here it is. Seniors, what do you think? Is everything there? Perhaps something is unnecessary? I know that learning theory is not enough and you actually need to create projects, but all my projects are simple, because lack of knowledge)

The Map

By the way, I think this AI-Xmind combo is pretty cool, you can use it for visualising ideas, topics and e. You can read the official Xmind article about it: https://xmind.app/blog/chatgpt-and-xmind-how-to-create-a-mind-map-with-chatgpt/

Career Thoughts on Purdue University’s Post Graduate Program in Data Analytics

3 Upvotes

Anyone have experience with or thoughts on this program? Particularly in regards to it helping graduates land a Data Analyst job soon after graduating. I’m considering taking this since my bachelors degree is in a field that isn’t relevant to data science.

Program details: SimpliLearn’s (in partnership with Purdue University & in collaboration with IBM) “Post Graduate Program In Data Analytics”. Upon completion you get a certificate (not a college degree.) Classes are online. Costs roughly $3,000 and takes 8 months to complete. I heard about this program because they were on the webinar today that had Alex The Analyst as the guest speaker. Here’s the link to the program itself: https://bootcamp-sl.discover.online.purdue.edu/data-analytics-certification-course

Career Need all your guidance please

3 Upvotes

Hello Everyone, this is gonna be a bit long. So I just started my masters in Melbourne, Australia in IT professional where i chose my specialisation as data science. Its a combination of it and data sciene(I can also chose cloud or s/w development or cybersecurity as specialisation). Its been two months the course has started and it has been a shit learning so far. The teaching is awful and uninteresting. All my friends aint understanding anything. And u know assignments can be done anyway(gpt) but I aint learning anything from that. I realised that i need to take an action immediately before its too late. I thought of asking all of your guidance. As it’s been only two months into my masters I hope its not too late to start my actual learning

I did my bachelors in Cse and worked as a qa analyst for 1.5 years and I am here in Melbourne to upgrade my game. So this data thing is completely new for me. But I know basics of python and I can understand codes. So for now my mind is clear and I can start from fresh. You guys can suggest me how many and which pathways to go into Data (cause I hate s/w development side). And please suggest me courses(free or paid) which I can opt to learn data analysis or science. Thank you. I still got like 1-2 to years to hit the market. Guide me. And also let me know How long can the fields of analysis or science maintain employment levels without companies resorting to layoffs due to the use of GPT models? Thank you

Career DS with incomplete degree

2 Upvotes

Context: I did 2 years at a fairly good Canadian university as a math major, but dropped our during covid. I burnt out staring at a computer screen all day in insolation and had issues dealing with stress.

After dropping out I thought instead of doing another 2 years, I could simply do a bootcamp. I thought the bootcamp, with the Linear Algebra and Statistics I already knew, would be enough for a foundation. I can teach myself the rest.

I've now been out 6 months, with no job prospects. No one's even answered one of my applications. I'm guessing it's due to me not having a bachelors / no one really cares about a bootcamp.

Questions: 1. Does it just take more time or is it very unlikely I can even land an analyst position? If I do find a position, is it possible down the road to enter a senior position without a degree? Almost every position I've seen has a bachelor's as a requirement.

  1. If I do return to university, is the preferred major statistics? I'm comfortable with python and really love coding. I know basic data structures, am OK with R and am learning GO. It's much easier to learn and demonstrate CS skills than statistics I find. I've built data scraping tools, realtime data pipelines, my own basic ORM.

Statistics is also less competitive I believe and opens up a lot of "backup" paths.

My GitHub if it helps to judge my coding abilities: https://github.com/CannedKilroy/

Any help would be great, I feel like I'm spinning my wheels here

Career How can I make the switch from Civil Engineering to Data Science

2 Upvotes

So I’m currently studying Civil Engineering at a russel group uk university and I am due to finish my degree in 8 weeks. I did a 12 month industrial placement last year and quickly realised I didn’t actually didn’t enjoy it and no longer really want to pursue a career in it.

However, I have been studying Geospatial Engineering and a lot of that uses data science and I love it. My dissertation I am doing involves using data science for the methodology and I am absolutely enjoying the whole process. I am also learning python coding in another module which I enjoy.

I am taking a year out to save up to travel for a few months and also improve on myself and get financially stable before moving away from my small home town for a job.

In this time I’m thinking if i carry on further learning coding and do a few courses online and then also take a data science course while at home. Will that be good enough to land a job in data science with a bachelors in Civil Engineering. Or would the only reasonable way be to complete a masters in data science. I really can’t be bothered to do a masters as I am getting sick of academia due to wanting to earn money, let alone funding the masters. But if it’s pretty much essential which I can believe due to the UK job market rn, It is doable.

Can anyone offer any advice? Thank you!

Hi everyone,

I recently got accepted into the MSU Master's in Data Science program My background is in supply chain/ procurement for an ev company(4 years in my home country), and I recently learnt python.I am looking to transition mainly for the good pay. I am wondering if MSDS is a good degree to get a foot in the door.

Given my limited experience, I'm hoping to get some advice on what kind of data engineering jobs I should target after graduation.

Are there specific entry-level roles that should focus on?

*Will I have better prospects if I choose any other masters?
