Everyone is prepping for LLM interviews.
Meanwhile, the question that's tanking candidates across fintech, big tech, and applied ML roles is:
"๐ ๐ฐ๐ถ๐ณ ๐ฎ๐ฐ๐ฅ๐ฆ๐ญ ๐ฉ๐ข๐ด 95% ๐ข๐ค๐ค๐ถ๐ณ๐ข๐ค๐บ ๐ฐ๐ฏ ๐ข ๐ง๐ณ๐ข๐ถ๐ฅ ๐ฅ๐ข๐ต๐ข๐ด๐ฆ๐ต ๐ธ๐ฉ๐ฆ๐ณ๐ฆ 0.5% ๐ฐ๐ง ๐ต๐ณ๐ข๐ฏ๐ด๐ข๐ค๐ต๐ช๐ฐ๐ฏ๐ด ๐ข๐ณ๐ฆ ๐ง๐ณ๐ข๐ถ๐ฅ๐ถ๐ญ๐ฆ๐ฏ๐ต. ๐๐ด ๐ต๐ฉ๐ช๐ด ๐ข ๐จ๐ฐ๐ฐ๐ฅ ๐ฎ๐ฐ๐ฅ๐ฆ๐ญ?"
If you flinched, you are not alone. ๐๐ฅ๐๐ฌ๐ฌ๐ข๐๐ข๐๐๐ญ๐ข๐จ๐ง is still the most interviewed topic in machine learning, and the questions are getting sharper, not easier.
๐ What's inside this compilation:
๐ Classification fundamentals
๐ Evaluation metrics: confusion matrix, ROC curves
๐ Handling imbalanced data
๐ Classfication algorithms
๐ Model training and hyperparameter tunign
๐ฌ Interview tip: More candidates fail classification rounds on evaluation than on algorithms. "What's wrong with accuracy?" "ROC-AUC or precision-recall?" "Your data is 99:1 imbalanced - now what?"
The first third of this list is dedicated to exactly these questions before touching a single algorithm. That's where the easy gains live.

No Seq2Seq โ no ChatGPT. It's that foundational.
Every modern AI system that reads one sequence and writes another - translation, summarization, speech recognition, code generation, traces its roots back to this architecture.
Most people know the name. But can you go deeper?
- Why does the encoder collapse everything into a single vector?
- What breaks down on long sequences?
- How does the forget gate decide what's worth keeping?
10 questions. RNNs, LSTMs, encoder-decoder design, attention, and the trade-offs that led to Transformers.

- they all rely on ONE family of models Sequence Models.
The reason they matter is simple: most real-world data isn't independent. Words depend on the words before them. Stock prices depend on yesterday. A pedestrian's next step depends on their last three. Traditional ML assumes i.i.d. data, and that assumption breaks the moment order matters.
๐ In this article, https://t.co/X5kU31dHVp breaks down everything you need to know:
๐น What sequence models are & why order in data matters
๐น Why traditional ML fails on sequential, non-i.i.d. data
๐น RNNs: the foundation, and their vanishing gradient flaw
๐น LSTMs: how memory cells solve long-range dependencies
๐น GRUs: a leaner, faster cousin of LSTMs
๐น Transformers: self-attention powering BERT, GPT & more
๐น 9+ real-world applications across industries
๐ฌ Interview tip: This question is a staple in NLP, Deep Learning, and Generative AI interviews. Interviewers use it because it tests three things in one shot: your grasp of the RNN โ LSTM โ GRU โ Transformer evolution, the ๐ธ๐ฉ๐บ behind each leap, and your ability to map theory to real products.

"Explain GPT architecture" sounds like a softball interview question, until the interviewer follows up with:
- Why decoder-only?
- How does causal masking work in self-attention?
- What changed between GPT-1 -> GPT-5?
- How do today's frontier models (Claude, Gemini, Grok, DeepSeek, Qwen, LLaMA) compare to GPT and to each other?
Most candidates can describe transformers. Far fewer can clearly walk through why GPT-style models are built the way they are, how they've evolved, and where the broader frontier-model landscape stands today.

The difference usually comes down to a handful of decisions:
โข Which optimizer fits your loss landscape?
โข How do you schedule your learning rate?
โข When does batch norm help, and when does it hurt?

A favorite at FAANG ML interviews, and for good reason. ResNet didn't just win ImageNet 2015. It unlocked the era of truly deep networks.
The numbers still impress:
โ 3.57% top-5 error on ImageNet
โ 152 layers: 8x deeper than VGG
โ Lower computational complexity than VGG-19
The breakthrough wasn't more layers. It was a reframing: instead of learning a direct mapping H(x), learn the residual F(x) = H(x) โ x. Skip connections did the rest, and that same idea now lives inside nearly every Transformer and LLM you've used this week.
What's inside the article:
๐ The "degradation problem": why deeper networks got worse, not better
๐ How residual learning fixes it
๐ BasicBlock vs. Bottleneck Block
๐ Side-by-side comparison: VGG-19, ResNet-18/34/50/152
๐ Stage-by-stage walkthrough of ResNet-18
๐ Video explanations included
๐ฌ Interview tip:
Bonus points if you connect ResNet to today's models. Look at the pattern side by side:
๐๐๐ฌ๐ง๐๐ญ ๐๐ฅ๐จ๐๐ค: ๐น + ๐(๐น), where ๐ is a small stack of convolutions
๐๐ซ๐๐ง๐ฌ๐๐จ๐ซ๐ฆ๐๐ซ ๐๐ฅ๐จ๐๐ค: ๐น + ๐๐ต๐ต๐ฆ๐ฏ๐ต๐ช๐ฐ๐ฏ(๐น), ๐ต๐ฉ๐ฆ๐ฏ ๐น + ๐๐๐(๐น)

This week made one thing clear: AI is no longer just a tech story; it's a geopolitical, economic, and infrastructure story all at once.
From classified defense partnerships to multi-hundred-billion-dollar cloud commitments, the lines between Silicon Valley, Washington, and the global power grid are blurring fast.
Leading labs are openly warning that we may be approaching a point where AI starts meaningfully accelerating its own development, while regulators race to build guardrails around the most capable models before they ship.
The takeaway? The next phase of AI won't be decided only by model benchmarks. It'll be decided by policy, power (literal and political), and capital flows at a scale we haven't seen in tech before.

Answer: https://t.co/THM5rEHbHA
"The cat sat on the mat because it was tired." Does "it" mean the cat, or the mat?
You knew instantly. So does GPT - thanks to self-attention. And masked self-attention is what stops the model from "cheating" by peeking at future words during training.
Self-attention is the single most important idea in modern NLP. It's the reason BERT understands context, GPT generates coherent text, and Claude can hold a conversation. Once you truly understand it, the rest of the Transformer falls into place.
๐ In this article, you'll learn
๐ What self-attention actually computes -> Query, Key, and Value explained
๐ How attention scores decide which words matter to which others
๐ Why masked self-attention exists -> and why GPT can't work without it
๐ BERT vs GPT: bidirectional attention vs causal (masked) attention
๐ PyTorch implementation of self-attention in just 30 lines of code
๐ฝ๏ธ Video walkthroughs that make the math click
๐ก Interview angle: "Explain self-attention" is a guaranteed question for any NLP, LLM, or applied ML role in 2026. The trap most candidates fall into: describing what it does instead of why it works. Strong candidates start with the intuition, ๐๐ฏ๐๐ซ๐ฒ ๐ฐ๐จ๐ซ๐ ๐ฅ๐จ๐จ๐ค๐ข๐ง๐ ๐๐ญ ๐๐ฏ๐๐ซ๐ฒ ๐จ๐ญ๐ก๐๐ซ ๐ฐ๐จ๐ซ๐ ๐๐ง๐ ๐๐๐๐ข๐๐ข๐ง๐ ๐ฐ๐ก๐๐ญ ๐ฆ๐๐ญ๐ญ๐๐ซ๐ฌ, then layer in the math.
