Skill Assessments
Validate your expertise with timed, industry-standard tests.
DL Group Test 01 — Neural Network Foundations
Covers Introduction to Neural Networks, Neurons & Perceptrons, and Activation Functions. Tests your understanding of the building blocks of any neural network — perceptron geometry, universal approximation, and activation characteristics. Ideal for warming up before deeper training-mechanics topics.
DL Group Test 02 — Training Mechanics
Covers Forward Propagation, Loss & Cost Functions, and Backpropagation. Tests how information flows through a network, how error is quantified, and how gradients propagate back. Critical for understanding why networks learn (or fail to).
DL Group Test 03 — Optimization & Architecture
Covers Optimizers and ANN Architectures. Tests gradient-descent variants, adaptive learning rates, momentum, and how macro-level architectural choices (depth, width, skip connections) affect training dynamics. Ideal prep for questions on training instability and scaling.
DL Group Test 04 — Regularization, Normalization & Initialization
Covers Regularization & Normalization and Weight Initialization. Tests dropout mechanics, BatchNorm vs LayerNorm trade-offs, covariate shift, and initialization schemes (Xavier, He, LeCun). Understanding this cluster is essential for training stable, generalizable networks.
DL Group Test 05 — CNN & Sequential Models
Covers CNN Architectures and RNN / LSTM / GRU. Tests spatial feature extraction, receptive fields, residual connections, and sequential memory mechanisms. A must-have before moving to Attention — these are the baselines Transformers replaced.
DL Group Test 06 — Attention, Transformers & Self-Supervised Learning
Covers Attention Mechanisms & Transformers and Self-Supervised & Contrastive Learning. Tests scaled dot-product attention, positional encodings, multi-head attention, and pretraining paradigms like SimCLR, MoCo, and MAE. Core to any modern ML interview.
DL Group Test 07 — Graph Neural Networks & Transfer Learning
Covers Graph Neural Networks and Transfer Learning. Tests message passing, graph pooling, expressive power (WL test), and transfer strategies (fine-tuning, LoRA, task arithmetic). Bridges structured-data reasoning with efficient model reuse.
DL Interview Mock — Easy 01
Broad-coverage easy mock interview simulating a first-round screening. One question from each major DL cluster: foundations, training mechanics, optimization, regularization, CNN, RNN, attention, and modern paradigms. Build confidence before moving to harder mocks.
DL Interview Mock — Easy 02
Second easy mock interview with fresh question selections across all 16 DL topics. Focuses on common definitional traps — same difficulty as Easy 01 but tests complementary concepts. Complete both easy mocks before attempting medium-level tests.
DL Interview Mock — Medium 01
Applied reasoning mock interview at medium difficulty. 12 questions covering the full DL pipeline — from neural net fundamentals and training mechanics through modern architectures and transfer learning. Simulates the applied ML engineer interview loop at mid-level companies.
DL Interview Mock — Medium 02
Second medium mock with fresh question selection. Emphasizes debugging intuition — gradient flow issues, normalization edge cases, optimizer quirks, and sequence modeling gotchas. Complements Medium Mock 01 by covering the remaining topic variants.
DL Interview Mock — Hard 01
Senior-level hard mock interview covering edge cases, production failure modes, and nuanced architectural trade-offs. 15 questions spanning all major DL topics — expect questions on loss spikes, attention saturation, BatchNorm pitfalls, contrastive collapse, and LoRA forgetting. Target: senior ML engineer or research scientist roles.
DL Interview Mock — Hard 02
Second hard mock with fresh question selection. Focuses on hardware-aware reasoning — FlashAttention, roofline analysis, quantization artifacts — alongside classic hard traps like exploding gradients, depthwise convolution latency, and knowledge distillation failure modes. Complements Hard Mock 01 with complementary concepts.
DL Elite Test 01 — Production Failures & Architecture Decisions
18-question elite screening for senior engineers and AI researchers. Every question targets production-grade judgment: Why does your training run spike at step 1200? Why does SimCLR collapse at small batch sizes? How does RoPE affect long-context extrapolation? Covers RMSNorm, DeepNorm, Neural ODE, MAE vs DINO, VAE posterior collapse, and weight tying. Requires deep architectural intuition, not just textbook recall.
DL Elite Test 02 — Optimization Internals & Debugging
18-question elite test targeting AI architect–level depth. Mix of hard MCQs and elevated medium questions that require synthesis: understanding why gradient checkpointing trades compute for memory, how LoRA rank affects task arithmetic interference, when depthwise separable convolutions hurt rather than help, and how link-prediction leakage poisons GNN benchmarks. Ideal as a final screening before staff/principal engineer or research scientist interviews.
