1,300 Jobs Gone. Because AI Can Now Do It Faster.
Glassdoor and Indeed just laid off 1,300 people yes, the same platforms that help people find jobs are now letting go of their own. Why? cz their parent company is going all-in on AI to “streamline” hiring. Most of these layoffs hit R&D, HR, and sustainability teams in the US. Even glassdoor’s CEO is stepping down. The plan now is to merge glassdoor into Indeed and let AI take over a big chunk of the backend work. Their CEO literally said “AI is changing the world, and we need to move faster and fix what’s broken. Today, about one-third of their code is written by AI. Soon, that could be 50%. And they’re not alone Microsoft, Google, Amazon… all are cutting jobs while letting AI do more of the work. Just last week, Intel cut 4,000 jobs, Microsoft let go of 6,000 CrowdStrike laid off 5% of its staff And all of this, even when profits were up. Scary, isn’t it?

    You have to find best fit box for the item (-1 in case of no box found)

  For example:

    Given 10,20,30,40,50,60,70 and 45

      You have to print 50

    Given 10,20,30,40,50,60,70 and 75

      You have to print -1

      Given 10,20,30,40,50,60,70 and 50

    You have to print 50

2. -----/

Round: TECHNICAL INTERVIEW
Experience: 1. Given an array of integers

you have to output sequence a1,a2,a3,a4,a5,a6,a7 such that a1a3a5a7

    For example:

    Given 10,20,30,40,50,60,70

      You have to print 10, 30, 20, 50, 40, 70, 60

At first, I gave answer using sorting. But my interviewer asked me to do this without sorting the input array, and I did it.

2. A simple question on Tree data structure which i don’t remember.

3. Questions related to my project.

Round: TECHNICAL INTERVIEW
Experience: 1. A matrix is given which is sorted row wise and column wise

You have to print the sorted order.

       2 3 4 5 7 8

       2 3 4 5 8 8

       3 4 4 6 8 9

       4 5 5 7 8 9

    You have to print sorted order

2. Questions related to my project during my internship.

Round: TECHNICAL INTERVIEW
Experience: 1.What happens when we type amazon.com

Relating to this the interviewer asked me every step in detail including all 7 layers of networks.

Protocols like: HTTP, HTTPS, DHCP, DNS, IMAP, POP, TCP, UDP etc. Their uses and differences.

2. Describe ACID property of a transaction (DBMS).

Round: HR Interview
Experience: Given a singly linked list, write a recursive method to reverse every 3 nodes in the list.
He asked me to inform if I have seen the question.I replied : Yes sir, it is the similar question I faced in coding round of Amazon-internship last year.
But he didn’t changed the question.
I solved it with a silly mistake which i corrected when mentioned.
