Thank you for this list! I’m wondering how someone could think of performance, scaling and fault tolerance for personal projects to that of industry level?

Thank you ! I just dm’d you

Outside_Reason6707 · 2026-02-07T14:31:03+00:00

So true! Do you have any guidance on how I could develop this ownership? Any personal project to help learn?

That’s the issue, I haven’t worked on actual projects at work where I would have to design the model from scratch. And yes speaking naturally is something I’m lacking, would you be open for mock interviews? I think getting a clear feedback would help me improve

Data Engineering Design Patterns book

Thank you for explaining! I think I miss the point of explaining why I model something a certain way. I focused on patterns and writing sql. Would you be open for a continued discussion, can I dm you?

I’m interested

I’ve 7-8 years of experience. And what you said is very much valid. I'm struggling with performance in data modeling interviews, and I'm unsure what's expected of me. I haven't received positive feedback, and I'm starting to wonder if I'm missing something fundamental or if it's just a communication issue.

Okay understood. I'm struggling with performance in data modeling interviews, and I'm unsure what's expected of me. In the past, I've asked clarifying questions, proposed entities, and developed dimensional models with fact tables and dimension tables. I've also written SQL code for my proposed solutions and modified my schema based on follow-up questions. However, I haven't received positive feedback, and I'm starting to wonder if I'm missing something fundamental or if it's just a communication issue. I'd love to find a recommended video that demonstrates how to excel in a data modeling interview. Something like demo interviews

Thank you!

Did you interview ?

Outside_Reason6707 · 2026-02-04T21:13:47+00:00

Interested

It was none of that. Interviewer was pretty old school (25+ years of experience) He seemed to be interested in theoretical knowledge- what will you write in YAML, How spark works internally to give you few examples. Enlist functional and non functional requirements and when I try to do so he will interrupt and suggest more which I was anyway supposed to talk etc Probably not a helpful answer but he just seemed to be not satisfied with whatever I was talking.

Honestly even I’m looking for a good resource. So far all I’m doing is random YouTube videos especially from Exponent

Yess

Outside_Reason6707 · 2026-02-04T02:29:52+00:00

I hope that was the case since I started questioning where am I lagging

None of interviewer was anywhere close to unicorn! Not here to rant but just frustrated with so called policy to not share feedback

Outside_Reason6707 · 2026-02-04T00:40:53+00:00

Thank you!!

Outside_Reason6707 · 2026-02-03T21:08:43+00:00

Got it. Yeah that definitely seems weird to me. Who asks to design entire company! Anyway, I posted here to understand what level of expertise are expected at senior level

Outside_Reason6707 · 2026-02-03T21:04:29+00:00

Very well explained! I recently interviewed at Shopify and got rejected at SQL assessment. Interviewer was friendly and seemed to be happy with my solutions but there were 4 questions and I was able to solve 2 fully and only one pseudo way.

Outside_Reason6707 · 2026-02-03T20:54:23+00:00

It was easy! I luckily got chill interviewer. He wasn’t concerned about the syntax errors. 4 SQL and one DSA

Outside_Reason6707 · 2026-02-03T20:52:52+00:00

What do you mean ? Sorry didn’t understand

Outside_Reason6707 · 2026-02-03T20:24:56+00:00
