Kritrima Prajna skill that every student must know


🔹 Core Skills (Still Mandatory – Baseline Expectations)

These are no longer differentiators, but minimum requirements:

  1. Data Structures & Algorithms (DSA)

    • Time–space tradeoff analysis

    • Problem-solving approach (not just final code)

  2. System Design Fundamentals

    • Scalable architecture

    • Component interaction and bottleneck analysis

  3. Debugging Skills

    • Identifying logical and runtime errors

    • Validating AI-generated code (AI often makes logic mistakes)


🔹 AI-Era Differentiator Skills (New Expectations)

These skills separate strong candidates from average ones:

  1. Prompt Engineering

    • Writing effective prompts to guide AI tools

    • Refining prompts for better code, tests, and explanations

  2. AI-Assisted Coding

    • Using AI for boilerplate code

    • Accelerating development without blindly trusting output

  3. AI-Assisted Debugging

    • Using AI to trace errors in large codebases

    • Asking the right questions to AI for root-cause analysis

  4. Error Handling & Validation

    • Detecting hallucinations or incorrect assumptions by AI

    • Verifying correctness, edge cases, and constraints

  5. Engineering Judgment with AI

    • Knowing when to use AI vs when traditional coding is better

    • Combining human reasoning with AI suggestions effectively


🔹 Advanced System & AI Integration Skills

Increasingly tested in system design interviews:

  1. Integrating AI into Existing Systems

    • Adding AI features into real-world workflows

    • API-based model integration

  2. Model Lifecycle Management

  • Versioning models

  • Monitoring performance and drift

  • Updating or rolling back models

  1. Trade-off Analysis for AI Systems

  • Cost vs performance

  • Reliability vs speed

  • Scalability vs complexity


🔹 Interview-Specific Practical Skills

Now commonly expected in interviews:

  1. Using AI During Live Coding

  • Efficient collaboration with AI tools

  • Demonstrating reasoning, not copy-paste coding

  1. Rapid Feature Delivery

  • Building or extending a feature in a short time (≈1 hour)

  • Managing unfamiliar codebases with AI support


🔹 Key Mindset Shift (Most Important)

  1. AI as a Co-Engineer, Not a Crutch

  • AI handles repetitive tasks

  • Engineers focus on:

    • Business logic

    • System architecture

    • Decision-making

    • Quality assurance


🔑 One-Line Summary

In the AI era, companies expect engineers who can think deeply, design systems intelligently, and use AI tools strategically—not just code well.

RAM Costs More… AI Does More… What Happens to Us?

The rise in RAM and other hardware prices is not merely a problem for consumers buying laptops or smartphones. It can also have an indirect impact on the future of engineering jobs and salaries . At first glance, hardware prices and an engineer's salary may seem unrelated. However, they are connected through one common factor: the cost of computing . Modern software companies depend heavily on servers, cloud platforms, GPUs, RAM, storage, and networking infrastructure. If these costs increase significantly, companies may become more careful about how they spend money on technology.  Will Higher Hardware Costs Reduce Engineer Salaries? Not necessarily—but they can change what companies expect from engineers . Imagine a company currently spends ₹10 crore on computing infrastructure and ₹5 crore on engineering salaries. If infrastructure costs rise substantially, the company may look for ways to improve productivity without increasing its workforce at the same rate. This could lead to...

Astra Is Not AGI Yet

  Astra Is Not AGI Yet: Why Computer Use Should Not Be Confused with Artificial General Intelligence The arrival of increasingly powerful AI agents has created a new wave of excitement around Artificial General Intelligence (AGI) . Every time an AI system demonstrates a new ability—using a computer, operating a terminal, browsing the web, writing code, or completing a multi-step task—the question quickly appears: “Is this AGI?” The answer is not necessarily. Recent demonstrations of Astra's computer-use capabilities have generated significant attention because the system can interact with a computer in ways that resemble human behavior. It can navigate interfaces, use applications, execute tasks, and work with a terminal. These capabilities represent a major advancement in AI agents, but computer-use capability alone should not be considered AGI . AGI Has Not Arrived—At Least Not by a Clear, Universal Definition One of the biggest problems in the current AI landscape is that there...

Engineers are better then Anthropic : HOW?

  Engineering in the Age of Powerful AI: What Students Must Do During Four Years of Engineering The rise of advanced AI systems like Anthropic’s Claude, OpenAI’s GPT models, and Google DeepMind has created anxiety among engineering students. Many are asking: “If AI can code, design, analyze, and even debug — what will engineers do?” The answer is simple but powerful: AI replaces repetitive tasks. It does not replace capable engineers. The role of engineers is evolving — from coders to AI-enhanced problem solvers, system thinkers, and decision makers. This article provides a complete four-year roadmap for engineering students to stay relevant, competitive, and future-proof in the AI era. The Reality of AI in Engineering AI can: Generate boilerplate code Suggest algorithms Debug simple errors Write documentation Automate repetitive development tasks But AI cannot: Understand unclear business requirements fully Take accountability for failures Make ethical decisions Manage production ...
