Everyone is excited about building AI agents.

But I think we’re about to discover a much bigger challenge:

Managing them.

Today, most conversations are about:

- Which model to use

- Which framework to pick

- How to automate workflows

Very few conversations are about:

- How do you monitor AI agents?

- How do you measure their performance?

- How do you know when they’re wrong?

- Who is accountable for their decisions?

We spent decades learning how to manage people and teams.

Now we’re entering a world where a single employee might work alongside multiple AI agents every day.

The next competitive advantage won’t be having AI agents.

Everyone will have them.

The advantage will come from knowing how to manage a workforce that includes both humans and AI.

That’s a skill most organizations haven’t developed yet.

And I think it’s going to become one of the most valuable leadership skills of the next decade.

What’s one thing you think companies are underestimating about AI agents ?

Q1. What does the CSS property float do?

Q2. How can you clear the sides of a floating element?

Q3. Why don't CSS properties apply when selectors are mixed up with different cases?

Q4. Are CSS properties case-sensitive?

Q5. Do margin-top or margin-bottom have an effect on inline elements?

Q6. Do padding-top or padding-bottom have an effect on inline elements?

Q7. Do padding-left, padding-right, margin-left, or margin-right have an effect on inline elements?

Q8. If you have a <p> element with font-size: 10rem, will the text be responsive when the user resizes or drags the browser window?

Q9. The pseudo-class :checked will select inputs with type radio or checkbox, but not elements. True or False?

Q10. In an HTML document, the pseudo-class :root always refers to the element. True or False?

Q11. Can the translate() function move the position of an element on the z-axis?

Q12. Which unit of measurement would you prefer among px, em, %, or pt, and why?

Q13. How do absolute, relative, fixed, and static positions differ in CSS?

Q14. What are the differences between visibility: hidden and display: none?

Q15. What are the differences between inline, block, and inline-block display types?

Q16. What are the properties related to the CSS box model?

Q17. Does overflow: hidden create a new block formatting context?

Q18. How can you apply CSS rules specific to a media query?

Q19. What is the use of the only keyword in media queries?

Q20. Does the screen keyword in media queries apply to the device's physical screen or the browser's viewport?

Q21. Can you name some pseudo-classes you have used in CSS?

Q22. How do you vertically and horizontally align a <p> element to the center inside a <div>?

Q23. How can you optimize CSS selectors for better performance?

Q24. How can you load CSS resources conditionally in a web page?

Q25. Why would you use sprites in CSS?

Q26. What is specificity in CSS, and how do you calculate it?

Q27. What is the shadow DOM in web development?

Q28. What do you know about CSS transitions?

Q29. Name some different CSS filters you can use to modify elements.

Q30. What are the reasons to use a CSS preprocessor in web development?

Q31. What is the difference between layout and positioning in CSS?

Q32. What is the difference between CSS Flexbox and CSS Grid layout systems?

Stay tuned for the answers of above questions :)

Below are the Episodes to watch:

Please do like share & subscribe to @codedecks

1. Hackerrank Test (60 mins)

This included 2 DSA medium level programming problems. One of the problems was from the Leetcode medium section on DFS based topics and other was from the String, Hashing topic.
After this, another assessment was given - Amazon Workstyle Assesment which takes 15-20 mins more.
Resources:
Interview Experiences

✅ Technical Interview Loop (4 rounds)

Round 1️⃣ (45 mins)

The first round was purely based on DSA, problem was from Trees topic. I was expected to first understand the problem, ask questions related to constraints or any other clarifications before moving to the solution part. After that he asked me one of the Leadership principle (behavioural question).

Round 2️⃣

This was the HLD(high level design) in which interviewer asked me to design a system which is already existing in Amazon.

Started with the Non-functional & Functional requirements, estimating the DB size, System architecture design, backend APIs, DB schema design, security & UI design.

Round 3️⃣

Next round was the LLD(Low Level Design) in which interviewer asked me to code one of the problem in the editor. The code should be modular, following SOLID principles, should be scalable, handling the exceptions, proper naming conventions. Also he asked one of the behavioural question in this round.

Amazon Leadership Principles:

Behavioural examples: https://docs.google.com/spreadsheets/d/1oBA6vanArm8gh79vzUnyJL-1kriLiGznYKh8gXAfD4s/edit

Round 4️⃣ - Bar Raiser Round

Amazon Bar Raisers are used as impartial interviewers unconnected to the position or group for which the applicant is applying. The interviewer can ask anything related to DSA, System Design or Leadership principle.

✅ Final Round - Offer Discussion

Finally, the HR discussion in which you can negotiate salary & ask if there are any doubts related to the interview. Preparing for the interview was made easy by my previous knowledge of problem solving and I had to revise System design topics.

These should help and for LPs you can prep from https://program.kraftshala.com/what-questions-to-expect-in-amazon-interview/

The process of establishing system aspects such as modules, architecture, components and their interfaces, and data for a system based on specified requirements is known as system design. It is the process of identifying, creating, and designing systems that meet a company’s or organization’s specific objectives and expectations. Systems design is more about system’s analysis, architectural patterns, APIs, design patterns, and glueing it all together than it is about coding. Because your application will be able to handle the architectural load, designing your system adequately for the requirements of your application will eliminate unnecessary costs and maintenance efforts, as well as provide a better experience for your end-users.

12. You should be ready to answer comparison based questions based on your project like why you have chosen XYZ technology in your project, what can be the other alternative and why you have not used it etc.

13. Read the Previous Interview Experiences of the company (glassdoor etc) before giving Online Test and Interview (Many of the concepts are repeated).

14. At last be ready with the HR and Situation based Questions and also read a little bit about the company before giving the interview. Don't come up with "My weakness is that I am perfectionist😆" and Don’t try to over smart. Simply say No if you don’t know something. Be honest.

Note : Grind Leetcode and read through the discussions. Will help you come up with multiple ideas to solve a problem. Just cram all the 180 questions by striver.

You can Practice Aptitude and Logical Reasoning Problems through indiabix.com
