I find small creators on Linkedin adding more value than Big Creators.

Eg: Small creators are teaching you the core concepts and things that matter a lot to new beginners.

Big Creators are busy with Polls like How many days are there in a week😂😂

What do think about this?

Here is my Free program for Students.
I don't want students to pay money from their pocket hence keeping it for Free. Let's call it Community.

𝗔𝗳𝘁𝗲𝗿 𝗚𝗮𝗶𝗻𝗶𝗻𝗴 𝗦𝗼𝗺𝗲 𝗽𝗼𝗽𝘂𝗹𝗮𝗿𝗶𝘁𝘆
Do you want to join FAANG, Join XYZ Academy's XYZ course?
That course actually cost Lakhs of Rupees.

Bhai isse acha toh apna hi course bech lete,
at least students would not be losing a lot of money.

I have seen institutes charging lakhs of Rupees for DSA, and Data Analysts courses (python, excel, powerbi) for more than a lakh rupees.

Have you encountered any such Influencers?
Just comment Yes or No.
Let's see How many of you have spotted such Doglapan.

𝗖𝗿𝗮𝗰𝗸𝗶𝗻𝗴 𝗶𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝘀 𝗮𝗿𝗲 𝘀𝘂𝗽𝗲𝗿 𝗲𝗮𝘀𝘆.
Focus on top interview Questions and start your preparation around the same.

Out of 10 interviews,
You might get rejected 7 times but still would crack 2-3 Offers.

𝗦𝘂𝗿𝘃𝗶𝘃𝗶𝗻𝗴 𝗮𝘁 𝗝𝗼𝗯 𝗶𝘀 𝗛𝗮𝗿𝗱.
If your fundamentals are not clear, Every day is a nightmare.
Connecting the dots is really important.

At Job, You should not be spending your time learning the concepts.
It should be a part of your interview preparation strategy only.

What do you think about this?

𝗪𝗵𝘆 𝘀𝗵𝗼𝘂𝗹𝗱 𝘆𝗼𝘂 𝗻𝗼𝘁 𝗧𝗿𝘂𝘀𝘁 𝗢𝗻𝗹𝗶𝗻𝗲 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲 𝗕𝗹𝗶𝗻𝗱𝗹𝘆?

Have you ever noticed, when you search Google to learn something you see the same Article is available in every popular Blog?

Yeah😂😂

But who writes these Articles?
❌ SME(Subject Matter Experts)
✅ SEO Experts(Search Engine Optimization Experts)

What they do, They search for the content online and copy the content and diagram from each other and just Paste it.

Most of the time you get good information, but what if you get the wrong Information?

The wrong information would be copied by everyone because it was not validated and ultimately consumed by the people who are new to it.

Proof: I was taking a session on the Collection framework and was feeling lazy to draw the diagram of the hierarchy so searched for a diagram online to use from the website itself.

What I noticed was wrong information everywhere.

Take this example, LinkedinHashSet should have extended from HashSet and LinkedHashMap should have been extended from HashMap.

I am not trying to highlight that mistakes cannot happen. But everyone makes the same mistake just because they are just copy-pasting each other's content and just creating their own diagram using the tools.

Search for the collection framework in google Images and you will be surprised to see the mistakes are copied everywhere.
