Here’s everything you need to know to pass the SQL data engineer interview in big tech!

AI and data engineering are so similar it's painful! - Agent workflows = data pipelines - Chunking text = data modeling - Embeddings = dimensionality reduction - Retrieval = indexing and partitioning - Vector search = join optimization - Prompt engineering = query tuning - Guardrails = data quality checks If you don't see how these parallels mean data engineers are going to take over the world, you're blind!

Je suis à mi-chemin de ma formation de Data Engineer sur DataExpert.io. J'ai déjà énormément appris, je me sens encore perdu sur beaucoup d'autres points. Cela me fascine bien plus que prévu j'aime le fait d'avoir encore tant de choses à approfondir. Merci @EcZachly

@realDGG Wow imagine companies paying software engineers to implement AI systems

@EcZachly I’ll just leave this here you dickhead

Hand coding is dead! All that’s left is: - solving actual business problems - system design and actual design What else are you learning at GTC?

Fundamental concepts every data engineer should know because they don’t really change → ANSI SQL → CAP theorem → OLTP vs OLAP → job orchestration → fact data modeling → data quality testing → distributed compute → idempotent pipelines → logging best practices → AVRO / Thrift schemas → flexible schema vs defined schema → slowly-changing dimensional modeling What else am I missing?

LLMs are going to make everyone software engineers the same way the social media made everyone "influencers" tons of people will try and almost everyone will fail the hard truth is that it always comes down to you; not a technology

@ruggyscruggy Weird they’re all level 40

rate the fire red team (im only 4 badges in)

People are complaining about AI generated bugs like they wrote 100% bug-free code before 2022

@bryan_johnson When the bar is “can you run for 2 minutes to not die” and people still can’t cross it

Get off dat ass. 8 minutes a day of vigorous exercise linked to a 36% lower mortality risk. Benefits start at 2.2 min/day.

The +0.5% S&P500 6 month stock market returns are interesting. Very few companies still growing and so many mid size names losing hundreds of billions! Gainers: - Intel: +82% - AMD: +22% - Walmart: +20% - Google: +20% - Apple: +8% - Airbnb: +6% - Nvidia: +3% - S&P500: +0.6% Losers: - Tesla: -6% - Amazon: -9% - Meta: -16% - Block: -20% - Netflix: -21% - Snowflake: -21% - Microsoft: -22% - Adobe: -30% - Snapchat: -37% - Coinbase: -40% - Oracle: -47% - Figma: -53% - Atlassian: -57% The market is already so bearish even though the S&P 500 Index has gone up slightly because of the overweightedness of big tech names in the index.

@BatVibes Slow bro overpriced af

You have exactly $15 to build a team of 6 Kanto Pokémon. • You must pick exactly 6 Pokémon. • If you go over $15, you lose. • Gen 1, R/B Who is making your final roster?

Since Paramount $PSKY won the $WBD bid, their stock shot up 30% and then collapsed. It's down 4% since winning the bid. $NFLX also shot up 30% since losing the big. It's still up 24% $WBD isn't a good deal and the epitome of the lady in the red dress of entertainment!

If Atlassian hadn't bought Loom, the last time I interfaced with an Atlassian product was in 2020. I'm proud to say I'm 6 years sober from JIRA tickets. On that note, I have fallen out of love with Loom. What alternatives are you using in 2026?

@panda_liyin @Zai_org Looks fire!!

Coding agents can make the impossible possible for more people. But many are still left out due to affordability. Thanks to our partner @Zai_org, we are offering all GLM models to our Pro users for free for the entire month of March. On top of this, we are providing women 50% off the Pro plan for one year. This is our joint effort to support the global adoption of AI coding tools and to support women in tech. GLM-5, GLM-4.7 FlashX, and three more models are included — among the best models today for production grade tasks. Watch how we built a doodle-to-pixel art app, from design and MVP to a fully working product. Hope you all enjoy it. 👏 Sign up at sylph.ai. Drop a comment or DM for the promo code.

@paulg Education products are difficult to keep from churning imo though

Churn is the worst reason to have slow growth. Churn means you're not just unknown, or that there's a big threshold to sign up. It means people are actually trying the product and deciding they don't like it.

@andrewbrown @Ndi_tah 🤣

@EcZachly @Ndi_tah Sorry, I did what to you now?

@xanderNLP Spoken like a true principal data engineer

@EcZachly Genius insight. WOW.

I regret becoming a Tableau certified professional back in 2015 for a few reasons: - I immediately left data visualization after getting certified - it had no impact on my career - I realized that you do need to write the code yourself if you want to make the biggest impact - nothing from the certification beyond visualization design was transferable outside Tableau Are there certifications you regret getting?

@maverickgu1b So nothing can change in your life 🤣

@EcZachly Please someone fund MLOPS microsoft certificate for me 🙏🙏
