Here is a powerful ๐๐ก๐ง๐๐ฅ๐ฉ๐๐๐ช ๐ง๐๐ฃ to help you land a job!
Most people who are skilled enough would be able to clear technical rounds with ease.
But when it comes to ๐ฏ๐ฒ๐ต๐ฎ๐๐ถ๐ผ๐ฟ๐ฎ๐น/๐ฐ๐๐น๐๐๐ฟ๐ฒ ๐ณ๐ถ๐ rounds, some folks may falter and lose the potential offer.
Many companies schedule a behavioral round with a top-level manager in the organization to understand the culture fit (except for freshers).
One needs to clear this round to reach the salary negotiation round.
Here are some tips to clear such rounds:
1๏ธโฃ Once the HR schedules the interview, try to find the LinkedIn profile of the interviewer using the name in their email ID.
2๏ธโฃ Learn more about his/her past experiences and try to strike up a conversation on that during the interview.
3๏ธโฃ This shows that you have done good research and also helps strike a personal connection.
4๏ธโฃ Also, this is the round not just to evaluate if you're a fit for the company, but also to assess if the company is a right fit for you.
5๏ธโฃ Hence, feel free to ask many questions about your role and company to get a clear understanding before taking the offer. This shows that you really care about the role you're getting into.
๐ก ๐๐ผ๐ป๐๐ ๐๐ถ๐ฝ - Be polite yet assertive in such interviews. It impresses a lot of senior folks.

3 Steps on how to upskill & learn any New Tech as Frontend Engineer ๐ฅ
1. Stop learning just the Code of the Tech. As you know with every version update Code changes. See React, lots of APIs have changed.
2. Every Framework, Library or Tech comes with a purpose to solve a problem. Learn whatโs the problem. People donโt release just for show off of New Tech.
3. Donโt just jump to YouTube Tutorial, โ15 mins of this Tech, that Techโ. Rather, refer Conferences, Talks, Tech Blogs, Podcasts by the Official People whoโve built it (No one knows better than them โก๏ธ)

Java developer - Realistic Approach ๐ช๐ฉต
1. Learn Java as a whole:
๐Beginner :
- Java Core: Java syntax , Collections framework , Exception Handling , Multithreading ,
File Handling
- Java Intermediate - JDBC , Design Pattern , Generics etc.
๐ชPro :
- Advanced Java - Lambdas , streams , time , concurrency utilities , JVM internals
- Design Patterns - Creational , Structural , Behavioral
2. Build Tools:
- Learn and use popular build tools like :
๐Beginner : Maven (Web development) Gradle (App development)
๐ชPro : Ant
3. Version Control:
- Master a version control system like Git. Master the skills for
๐Beginner : Github
๐ชPro : GitLab , BitBucket
4. Command Line (This can be done parallel to the above 4)
Believe me when it comes to Java development Command line skills will be a boon for you guys.
Start with the basics for eg : install and setup java with Command Line only.
Start using Linux distributions ( it's very necessary ) go to a virtual box or dual boot your systems with any of Ubuntu , Kali Linux , Manjaro etc
5. Learn Servlets and JSP and then go for a framework ( Spring boot
