PreGrab

PreGrab is a venture that wants to tap into the pre-owned products market. We have kicked off from being a market-place for dealers of pre-owned products and will be primarily focusing on the needs of the buyers of these products. Once having established ourselves in our core business competencies, we aim to expand into B2B and C2C avenues. The problem we aim to solve is of the lack of reliability and visibility of these products from a buyer’s viewpoint. All the present arrangements in the market (online and offline) fail to provide these deliverables leaving the market highly untapped and the core problem unsolved.

In 1959, Dashrath Manjhi’s wife died because a mountain stood between his village and the nearest hospital.

He didn’t blame fate.
He picked up a hammer and a chisel.

For 22 years, he broke that mountain alone and built a road where none existed.

At topmate.io we are at our Mountain moment.

Our semi-monolithic architecture helped us move fast. Now, our exponential growth is testing its limits. Entropy is rising. Systems need to be reimagined, not patched.

We need our Manjhi!

We need someone who has been there and done that. While I love freshers, here we would need at least 3-4 years of experience folks in hardcore backend. Language and tech don't matter.

Ideal candidate - 4 years of experience working in a Series B startup who has seen their journey from the start.

If you have been through the phase where suddenly entropy increased, systems started to shatter due to unprecedented growth, and then you were the one to calm the systems down by revamping older services. Well, you are my ideal candidate!

Here is your chance to disrupt the creator economy and turn on it's head!

Many people are criticizing the candidate in this story, but I see it differently.

Hiring is a two-way street.

Companies often take days or weeks to respond, pause hiring, or move on without updates. Candidates are expected to simply wait and understand.

But when a candidate keeps exploring better opportunities, suddenly it becomes unethical.

Also, companies themselves frequently base offers on current salary. Two people can join the same role and do the same work, yet one might earn 2x more just because of their previous pay.

Let’s be honest - money runs life. People naturally try to secure the best opportunity they can.

In this market we’ve also seen lowball offers, delayed joining (especially in campus hiring), and even offer revocations.

So if companies optimize for their interests, it’s fair that candidates do the same.

The real answer is simple: clear communication and mutual respect on both sides.

Money is important specially for men, got rejected ( many of my friends too) for being at low package 🥲

She was clearly giving signals…
But I was busy understanding Advanced C++.

And honestly, 𝐂++ bhi kuch kam toxic nahi hai 💀

Here are some “reasons” why 👇

1️⃣ 𝐏𝐨𝐢𝐧𝐭𝐞𝐫𝐬 & 𝐑𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞𝐬
Relationship bhi pointer jaisa hi hota hai…
Galat handle kiya -> Segmentation fault 💥

2️⃣ 𝐌𝐞𝐦𝐨𝐫𝐲 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭
Manual ho ya relationship…
Free karna bhool jao → Memory leak 😶

3️⃣ 𝐔𝐧𝐝𝐞𝐟𝐢𝐧𝐞𝐝 𝐁𝐞𝐡𝐚𝐯𝐢𝐨𝐫
C++ me bhi unpredictable…
Aur relationships me bhi 🙂

4️⃣ 𝐓𝐞𝐦𝐩𝐥𝐚𝐭𝐞𝐬 (𝐆𝐞𝐧𝐞𝐫𝐢𝐜𝐬)
“Ek hi code sab pe kaam karega”
Reality: Edge cases ruin everything

5️⃣ 𝐌𝐮𝐥𝐭𝐢𝐭𝐡𝐫𝐞𝐚𝐝𝐢𝐧𝐠 & 𝐑𝐚𝐜𝐞 𝐂𝐨𝐧𝐝𝐢𝐭𝐢𝐨𝐧𝐬
Tum soch rahe ho kuch aur…
Wo expect kar rahi hai kuch aur…
→ Deadlock 🤝

6️⃣ 𝐂𝐨𝐧𝐬𝐭 𝐂𝐨𝐫𝐫𝐞𝐜𝐭𝐧𝐞𝐬𝐬
Log bolte hain “I’ll never change”
C++ bolta hai: const ka matlab samajh pehle 😌

7️⃣ 𝐓𝐢𝐦𝐞 𝐂𝐨𝐦𝐩𝐥𝐞𝐱𝐢𝐭𝐲
Simple lagta hai…
But worst case -> O(n²) emotions 😭

Moral of the story:
Debugging C++ is still easier than decoding signals 😌

𝐌𝐨𝐬𝐭 𝐜𝐨𝐝𝐢𝐧𝐠 𝐢𝐧𝐭𝐞𝐫𝐯𝐢𝐞𝐰𝐬 𝐛𝐞 𝐥𝐢𝐤𝐞 - 

𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝗲𝗿:“Solve Two Sum.”
𝗠𝗲 : opens HashMap confidently 😌

𝐓𝐰𝐨 𝐒𝐮𝐦 is that classic friend who just wants a pair.
𝐓𝐡𝐫𝐞𝐞 𝐒𝐮𝐦 is the dramatic upgrade. Now we need a trio.

Quick recap:
--------------

✅ 𝐓𝐰𝐨 𝐒𝐮𝐦
 Store numbers in a map
 Check target minus current
 Done in O(N)

✅ 𝐓𝐡𝐫𝐞𝐞 𝐒𝐮𝐦
 Sort the array
 Fix one number
 Use two pointers
 Welcome to O(N²)

Same idea. More chaos. More loops. 😄

Funny how one extra number turns “easy win” into “think harder”.

Two sum and Three Sum

Most people practice LeetCode in a way that feels productive… but doesn’t actually prepare them for interviews.

A few habits that make practice much more effective:

1️⃣ 𝐃𝐨𝐧’𝐭 𝐣𝐮𝐬𝐭 𝐬𝐨𝐥𝐯𝐞 - 𝐮𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝 𝐭𝐡𝐞 𝐩𝐚𝐭𝐭𝐞𝐫𝐧
Sliding window, monotonic stack, prefix sum, two pointers, BFS/DFS… many questions are just variations of the same ideas. Recognizing patterns is what saves time in interviews.

2️⃣ 𝐒𝐨𝐥𝐯𝐞 𝐰𝐢𝐭𝐡 𝐚 𝐭𝐢𝐦𝐞𝐫
Give yourself 25 – 40 minutes per problem. Interviews are timed, and practicing under time pressure trains your decision making.

3️⃣ 𝐔𝐬𝐞 𝐠𝐨𝐨𝐝 𝐯𝐚𝐫𝐢𝐚𝐛𝐥𝐞 𝐧𝐚𝐦𝐞𝐬 𝐚𝐧𝐝 𝐰𝐫𝐢𝐭𝐞 𝐜𝐥𝐞𝐚𝐧 𝐜𝐨𝐝𝐞
Interviewers look at readability. Clear variable names and structured code make your thought process easier to follow.

4️⃣ 𝐄𝐯𝐞𝐧 𝐢𝐟 𝐲𝐨𝐮 𝐬𝐨𝐥𝐯𝐞𝐝 𝐢𝐭, 𝐫𝐞𝐚𝐝 𝐨𝐭𝐡𝐞𝐫 𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬
Sometimes there’s a cleaner trick, a different data structure, or a more optimal approach you didn’t think about.

5️⃣ 𝐓𝐫𝐲 𝐯𝐢𝐫𝐭𝐮𝐚𝐥 𝐜𝐨𝐧𝐭𝐞𝐬𝐭𝐬 𝐛𝐞𝐟𝐨𝐫𝐞 𝐫𝐞𝐚𝐥 𝐨𝐧𝐞𝐬
Do ~20 virtual contests with a strict 1-hour timer. It builds speed, pressure handling, and prioritization.

6️⃣ 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞 𝐦𝐨𝐜𝐤 𝐢𝐧𝐭𝐞𝐫𝐯𝐢𝐞𝐰𝐬
You can do them with friends, platforms like pramp.com, or paid sessions on Topmate.

7️⃣ 𝐑𝐞𝐜𝐨𝐫𝐝 𝐲𝐨𝐮𝐫𝐬𝐞𝐥𝐟 𝐞𝐱𝐩𝐥𝐚𝐢𝐧𝐢𝐧𝐠 𝐭𝐡𝐞 𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧
Try recording your voice or video while solving. You’ll quickly notice where you hesitate, overthink, or struggle to explain clearly.

LeetCode is not about solving the most problems.

It’s about training how you think, communicate, and perform under pressure.

Imagine this situation.

You have a 10 GB log file.

Every 2 hours your system downloads and copies it to another server.

But most of the time the file does not change.
Maybe only 100 KB of new logs were added.

Yet the system still transfers the full 10 GB again.

𝗧𝗵𝗮𝘁 𝗺𝗲𝗮𝗻𝘀 𝗮 𝗹𝗼𝘁 𝗼𝗳 𝘄𝗮𝘀𝘁𝗲𝗱:
❌ Network bandwidth
❌ Disk I/O
❌ Time

This is where 𝐫𝐬𝐲𝐧𝐜 becomes very powerful.
💡 The smart idea behind 𝐫𝐬𝐲𝐧𝐜

Instead of copying the whole file, 𝐫𝐬𝐲𝐧𝐜 only 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿𝘀 𝘁𝗵𝗲 𝗰𝗵𝗮𝗻𝗴𝗲𝗱 𝗽𝗮𝗿𝘁𝘀 of the file.

So if only a small portion changed, only that part moves across the network.

Think of it like this.

𝐍𝐨𝐫𝐦𝐚𝐥 𝐜𝐨𝐩𝐲 works like:
📦 Send the 𝗲𝗻𝘁𝗶𝗿𝗲 𝗯𝗼𝘅 𝗮𝗴𝗮𝗶𝗻 𝗲𝘃𝗲𝗻 𝗶𝗳 𝗼𝗻𝗹𝘆 𝗼𝗻𝗲 𝗶𝘁𝗲𝗺 𝗶𝗻𝘀𝗶𝗱𝗲 𝗰𝗵𝗮𝗻𝗴𝗲𝗱.

𝐫𝐬𝐲𝐧𝐜 works like:
📦 Send 𝗼𝗻𝗹𝘆 𝘁𝗵𝗲 𝗶𝘁𝗲𝗺 𝘁𝗵𝗮𝘁 𝗰𝗵𝗮𝗻𝗴𝗲𝗱.

📊 Simple Example
Suppose this file exists on two servers.

𝐎𝐥𝐝 𝐟𝐢𝐥𝐞 𝐨𝐧 𝐝𝐞𝐬𝐭𝐢𝐧𝐚𝐭𝐢𝐨𝐧
[A][B][C][D][E]

𝐍𝐞𝐰 𝐟𝐢𝐥𝐞 𝐨𝐧 𝐬𝐨𝐮𝐫𝐜𝐞
[A][B][𝗫][D][E]

Only C changed to X.

𝐍𝐨𝐫𝐦𝐚𝐥 𝐜𝐨𝐩𝐲
----------------
System transfers : A B X D E
Full file transfer.

𝐑𝐬𝐲𝐧𝐜
-------
System detects that A B D E already exist.
So it transfers only - 𝐗

Destination rebuilds the final file using existing blocks.
𝐑𝐞𝐬𝐮𝐥𝐭
[A][B][𝐗][D][E]

Much faster and much less data moved.

📉 Real world numbers

Imagine this scenario.
File size
 📦 20 GB
Change in file
 ✏️ 5 MB
Runs per day
 ⏰ 12 times

Using 𝐍𝐨𝐫𝐦𝐚𝐥 𝐜𝐨𝐩𝐲
- 𝟐𝟎 𝐆𝐁 × 𝟏𝟐 = 𝟐𝟒𝟎 𝐆𝐁 𝐭𝐫𝐚𝐧𝐬𝐟𝐞𝐫 𝐩𝐞𝐫 𝐝𝐚𝐲

Using 𝐫𝐬𝐲𝐧𝐜
- 𝟓 𝐌𝐁 × 𝟏𝟐 = 𝟔𝟎 𝐌𝐁 𝐭𝐫𝐚𝐧𝐬𝐟𝐞𝐫 𝐩𝐞𝐫 𝐝𝐚𝐲

That is a massive improvement.

🧠 How 𝐫𝐬𝐲𝐧𝐜 does this
𝐑𝐬𝐲𝐧𝐜 breaks files into small blocks.

Then it compares those blocks between the source and destination.
If a block already exists on the destination, 𝐫𝐬𝐲𝐧𝐜 reuses it.
If a block changed, 𝐫𝐬𝐲𝐧𝐜 transfers only that block.
So the final file is rebuilt using a mix of
 🔹 existing blocks
 🔹 new blocks
This technique is called delta transfer.

🌍 𝐖𝐡𝐞𝐫𝐞 𝐭𝐡𝐢𝐬 𝐢𝐝𝐞𝐚 𝐢𝐬 𝐮𝐬𝐞𝐝
This concept powers many modern systems.
 📁 Backup systems
 ☁️ Cloud storage sync
 📦 Linux package mirrors
 📂 Dropbox style file sync
 🐙 Git style data transfer

All of them try to transfer only what actually changed.
⚡ One simple takeaway

Before moving huge data, ask one question. Did anything actually change?

If the answer is small, only move the difference.

That is the magic of 𝐫𝐬𝐲𝐧𝐜.
