Mast interview laga tbh most of these things ke liye I'm prepped isliye thoda achha laga some things jaise spring boot mujhe padhne padenge although!

Super helpful! Thanks Kajal and all the best on your new role! The title of this video can also be Java Dev Interview questions (it covers almost everything one should prepare).
1. **Application Process**: The candidate applied through a drive organized by Airtel. They were informed about the interview format, which included multiple rounds on the same day focusing on data structures, algorithms, and project-related questions. 2. **First Round**: - Questions covered basic concepts such as: - What is anagram? - Finding a missing number in an unsorted list. - Sorting custom objects using Java. - Multithreading concepts, specifically the differences between sleep and wait. - Equals and hashcode contract. - The interviewer asked about Spring Boot, including writing an API to retrieve user data and handling dependency injection. - Additional topics included cyclic dependency resolution and extracting unique keys from JSON objects. 3. **Second Round**: - It was longer than expected, lasting about two hours. - Focused on advanced topics such as: - Implementing a Comparator. - Exception handling strategies. - Output-based questions related to method overriding. - Questions about RabbitMQ and Kafka, including handling bulk messages and scenarios where the queue size limit is reached. - Discussing design patterns, especially the Singleton pattern. - Questions on synchronization in multithreading environments and using thread pools. 4. **General Advice**: The candidate emphasized the importance of understanding core Java concepts (like collections, streams, and multithreading) and encouraged preparation around real-world scenarios, especially if mentioned in the resume. 5. **Outcome**: After completing both rounds, the candidate was selected for a final manager round, indicating the interview went well.
Can you please make a separate video for important questions or you may start a series of important questions of different topics of java and frameworks mostly asked.
A suggestion to you, create a playlist and teach different languages in them. And use google ads and beta promotion to spread your videos to reach more views. Also make this interview questions and latest asked questions ❤
Sabse bada reason bachon ka company mai na lagne ka reason hai ...pta hi ni hota kab kese kha recruitment nikli 😔...mam plz how to make resume par video bna dijiye ...usme bhi kya likhna hai😂is par ni ...kese overleaf par proper bnana hai uski video chahiye 🙂
Congratulations 🎉 One question Does now a days Kotlin is more preferred then java for spring boot back-end development if organization has front end Android native kotlin code
I am not from Java side , am data analyst but wanted to jump into java backend development. Conceptually i can cover from several sources you mentioned, how to have knowledge of project? Any UA-cam channels or resources??? Help will be appreciated!!
I got offer from both epam and airtel but joined epam as I got better package at epam and they offered flexibility of WFH. And work i got is also good.
Ma'am can your share the best UA-cam channel for interview preparation based on java , spring boot and advanced concepts like kafka , microservices like that 🌿
Hello maam Suppose you work on java and you know basics of some concepts and deeply about some concepts, but if your interviw is scheduled after 3 days, how to cover all topics in revision
Very informative video. Can you pls tell me what concepts do i need to know to be able to get hired as a fresher? Im very confused as different people say different things. Somebody says learn java , advanced java, collections, multi threading , spring ,springboot etc and some say basics would be fine. Im in a dilemma and can't gather enough courage to apply for any requirement.
Iam working in an mnc but not related to java project but iam much interested yo become become java developer and the required tech stack how can I show case the experience while shifting to other company and for shortlisting the resume and work experience what I should fo to become java developer
Thank you Kajal for sharing your interview experience in such details. It will be going helpful for all who preparing for the internship or jobs in this summer.
Im at a worst support role with only twch knowledge of linux. I want to switch to java or python ( i have covered by myself for both full stack ). How can i fake it to get as a developer role white switching ? Im not good at lying 😅
Thn dont lie simply add your support role learn java makr project and explain them you were learning all by yourself may be the package wont be great initially but will be improved with tym.
Hello ma'am, Ma'am I have a question that what is the eligibility criteria for junior software developer role in Airtel. Do they consider fresher for the role ?
Here you mentioned project i have doubt is this your personal project or the project you had worked in company also do we really need a personal project to show in resume for experience java developer?
Hi Kajal, I have 4 years of IT industry experience and around 3 years of experience as a Java developer. I feel stuck with a low salary and in one organization. For a few days, I've been watching your YT videos. Thanks for making it. It's helping. I have a question. How many months did you spend preparing for interviews, or did you prepare while giving interviews?
@@kajalgoyal3902 I am also looking for job change as Java dev and left with few days of NP. Can you share recruiter details if not an issue, sent you connect request in LinkedIN.
aur kajal currently now i am in second year of BE engineering can you tell me how I should prepare!!! and also, I want 8LPA to 12LPA. and after all my preparation will you refer me?
This video is so doubtful for me, Do companies really ask these many questions to the 3 year experienced developer, because the questions are like to be asked to the 4 to 6 year experienced developer?
Hi! I am akash and currently persuing mca i had completed one year and i want to just know How much time it will take to learn java and what filds are enough to land a job .
