Can You Explain The Ending Of Grokking The System Design Interview?

At the company's annual gala, the CEO announced that this year's top sales performer would receive a two-million-dollar year-end bonus. I was the top performer. However, my manager called me into his office the very next day and explained that the company was cutting costs and improving efficiency. As a result, my bonus had to be reduced. I initially assumed everyone's bonus was being cut. Then, I found out I was the only one getting shortchanged. Even worse, they handed my position to a useless coworker who could barely do the job. I understood everything immediately. 'So this is how it is. You're tossing me aside after you got what you wanted from me.' Fine. I stopped putting in any effort from that day forward. I clocked in, did the bare minimum, and watched the company slowly fall apart. Sales began to drop month after month. Even the major clients I had already secured began withdrawing their investments. That was when the CEO finally panicked. He showed up at my front door, begging me to fix things. I kicked the door open and looked down at him. "You think a garbage company like yours deserves my help?"

The HR manager slid a severance agreement across the table and said coldly, "You're fired." I froze. "Why?" Just one week ago, my boss had praised me in the company meeting and called me one of the team's most valuable people. The HR manager shrugged. "Ms. Lyttle, you're already 35. You don't have the energy of younger employees anymore, and you're not what you used to be. You no longer fit the company's future." I joined this company when I was 29. Over the past six years, I wrote countless lines of code and worked through more sleepless nights than I could remember. Every time the company faced a major system failure, I led the emergency response and saved it from catastrophic losses. And now they were telling me I was too old and too slow. I laughed in disbelief. "So you've already copied all my experience and skills into an AI, haven't you?" The HR manager paused for a moment before answering confidently, "AI never gets tired, never takes time off, and never asks for a raise. Once the company has an employee like that, why would we keep you?" I looked at her. "Are you sure the AI has learned everything I know?" She smiled. "Absolutely." The moment I heard that, I finally relaxed. Long ago, I had already hidden a trap inside my code to keep my skills from being copied. The moment their AI employee went live, the company would only have three days before everything fell apart.

After a grueling year of training abroad on the company's dime, I came home holding an OEM certification for our high-end production line. Only three people in the country had it. I couldn't wait to cash in my stock options and finally give my girlfriend, Nora, a home of our own. But when I got back to the office, there was no celebration waiting. Just three notices. [Finance: $50,000 travel reimbursement rejected. $20,000 in salary frozen as a performance hold, to be released after your review is passed.] [HR: Your sponsored training carries a mentoring obligation. You must train three qualified technicians within one month of returning, as your assessment. Fail, and your travel costs will not be reimbursed and your frozen salary will be forfeited.] [Direct Manager, Kevin: Turn over all core technical documentation. Effective tomorrow, you're reassigned to the factory floor for mentoring.] I gripped the three notices and headed for the manager's office to demand an explanation. I pushed the door open and froze. Nora, my girlfriend of three years, was sitting on Kevin's lap, her clothes half undone. Our eyes met. All she gave me was one cold line. "Ethan, since you've already seen it, let's just break up." I backed out of the office without a word. I walked past all the eager faces waiting for a show, went back to my desk, and finally answered the email that had been sitting in my inbox for a week. [I've decided to accept your offer. I can start in a month.] One month. Everything this company owed me, I was going to take back myself.

I had been managing the company’s warehouse software for five years. Then the new manager came to me out of the blue, saying I didn’t understand frontline operations and that I was being fired. Looking at the five-thousand-dollar severance, I just nodded. “Fine.” He patted my shoulder after seeing me so compliant and started lecturing. “Young people should be out on the line, moving boxes! What’s the use of sitting in the office staring at data every day? “We’re a logistics company. Strength is what matters, not a tech geek like you!” I glanced at the high-end gaming computer in his office and obediently replied, “Yes, Mr. Fuller. Lesson received.” Maybe I had been too comfortable these past few years, and he thought I was dispensable. So, I handed over my ID badge and casually deleted all my personal login keys from my computer. Little did he know that the entire warehouse logistics, inventory management, and route planning software had been coded by me. I had let the company use it for free simply because the place was close to home and the work was easy. Now that I was gone, the system running on my personal cloud server was naturally inaccessible. Tens of thousands of items in the warehouse ground to a halt. As for any commercial software that could replace my system, a year’s subscription would cost exactly one thousand times my severance.

I'm the type who has the urge to overshare my life with him. It can be anything, be it the flowers blooming by the side of the road, the unpleasant coffee I end up having, or the sunset I've seen when I'm on my way home from work. Heck, when I think of Edwin Howell all of a sudden, I can't resist texting him at all. His replies are always short and perfunctory, though I suppose they count as a form of response from him. Hence, over the past six months, I've relied on these cold-sounding yet present replies to give me enough strength to deal with the engagement party, go wedding gown shopping, and choose the wedding venue all by myself. Somehow, I've managed to hang in there till the week before the wedding. But five days before the wedding, I discover an AI program that's installed within Edwin's computer. It can categorize every single sentence that I've sent to Edwin and extract the keywords. Then, it'll draft the most perfunctory responses that will never go wrong. If I miss Edwin, the AI will reply, "Mm-hmm." If I feel aggrieved, the AI will reply, "Got it." When I try to vent my frustrations to Edwin, the AI will reply, "Don't make such a big deal out of it." It turns out that Edwin isn't the one who has been responding to my need to overshare. The thing is, he has been texting another woman nonstop in another private chat. They talk about anything and everything under the sun, from exchanging simple good mornings and good nights to asking, "What are you having for lunch today?" and "Do you wanna go to the beach someday?" Finally, I realize that Edwin isn't the silent type who keeps his love in. If anything, he's the flashy type who will proclaim his love anywhere, anytime. It's just that… his love has never been mine to have. As for me, I've finally made up my mind to stop spending my life waiting for a response that will never come.

At the end of the year, the company made employees vote on who would be laid off. In front of the boss, the votes were read aloud one by one. Natalie Reed. One vote. Natalie. Two votes. Natalie... thirty votes. All thirty people on my team had voted me out. I clenched my fists and looked around at my coworkers. Every single one of them avoided my eyes. Maggie Turner was the oldest on the team. I knew she had to pick up her kid, so whenever she could not finish her work and had to rush to her kid’s school, I stayed behind and cleaned up after her. Dylan joined last year. He was losing sleep every night over money for his wedding. I squeezed time out of my own schedule, helped him complete his project, and got him a two-hundred-thousand-dollar bonus. And the trainee closest to me started trembling the moment I looked at her. She looked just as timid as she had when her hands shook and spilled wine all over a client. Back then, to fix the mess for her, I apologized to the client and drank until I had a stomach hemorrhage. Only then did she pass probation. I could not help feeling hurt. The boss looked at the result and asked if I had anything to say. I took a deep breath and asked everyone on the team, “Why did you vote for me?” My timid trainee suddenly found her courage. “Because you always pretend to help people, then steal our credit.” “Otherwise, how could someone as useless as you become the top salesperson?” I laughed, took off my employee badge, and placed it on the table. A week later, my boss was kneeling outside my door, begging me, the so-called useless one, to come back to the company.
