🚀 Empower your career with data engineering skills and secure your dream job in this growing field⚙️

✔️ After receiving a lot of queries, I've made some revisions to my original suggestion and I highly recommend following this exact sequence. Trust me, it will make things much easier for you.

♻️ It's easy to get lost in the vast amount of information available when it comes to learning new skills, especially in the field of data engineering.

🔗 However, with a solid roadmap and some dedication, it is possible to enter the field of data engineering in 2023.

Here are some steps you can follow to make sure you're on the right track -

🔶 Learn RDBMS, NoSQL databases, SQL, and data warehousing concepts :

As a data engineer, you'll be working with large amounts of data stored in databases. Familiarize yourself with different types of databases and how to query them using SQL. Learn one RDBMS and one NoSQL database, then familiarize yourself with data warehousing concepts.

1. Learn Data Warehousing concepts - https://lnkd.in/eKnVbFAB
2. Learn MySql - https://lnkd.in/efk-Mi3c
3. Learn and practice SQL - https://lnkd.in/efMKFkfX
4. Learn Azure Cosmos DB - https://lnkd.in/eNVyc6Mq
   
🔶 Learn Python and PySpark :

These are essential tools for data engineers.

1. Python: https://lnkd.in/e5rCbvP8
2. PySpark : https://bit.ly/3Vu34Ev

🔶 Learn Bash, Airflow and Kafka :

These tools will help you automate and streamline data processing tasks. You will also lear how to create data pipelines.🔩

https://lnkd.in/eyN6u2yd

🔶 Learn Git and the basics of CICD :

These skills will help you work collaboratively on data engineering projects and ensure smooth deployment.

Git - https://lnkd.in/eX_Q8s99
Basics of CICD - https://lnkd.in/epKGivFY

🔶 Learn Azure Databricks and Data Lakes :

Azure Databricks - https://lnkd.in/eBij4akJ
Learn Data Lakes - https://lnkd.in/eQ9xxAJT

👉 Create a standout resume by showcasing your skills and experience in data engineering.

👉 Enhance your portfolio by completing various data engineering projects and sharing them on GitHub.

👉 Seek out opportunities in data engineering by applying to relevant positions

Optional Learning -

1. Learn Data Structure and Algorithms
2. Learn AWS or Azure services dedicated for data engineering works.
   
By following these steps and dedicating yourself to learning and gaining experience, you can become a data engineer in 2023. Good luck on your journey!

Instead of learning solutions of LeetCode questions, understand patterns! 🙂

𝑴𝒖𝒔𝒕 𝑺𝒂𝒗𝒆 𝒂𝒏𝒅 𝑺𝒉𝒂𝒓𝒆 !!!!

For ex.

If input array is sorted then
- Binary search
- Two pointers

If asked for all permutations/subsets then
- Backtracking

If given a tree then
- DFS
- BFS

If given a graph then
- DFS
- BFS

If given a linked list then
- Two pointers

If recursion is banned then
- Stack

If must solve in-place then
- Swap corresponding values
- Store one or more different values in the same pointer

If asked for maximum/minimum subarray/subset/options then
- Dynamic programming

If asked for top/least K items then
- Heap

If asked for common strings then
- Map
- Trie

Else
- Map/Set for O(1) time & O(n) space
- Sort input for O(nlogn) time and O(1) space
