 Good morning guys. I hope everyone is doing great. So today in this video, we'll be sharing the interview questions of Nagarro So this video was contributed by one of our subscriber friend firstly. Thanks to him and here is the mail What we have received from him Nagarro interview question Hi team as commented on video sharing my interview experience with Nagarro There were three rounds in total one that is like one is online test one is technical or Technical virtual or online route and HR round my experience is three place years topics to brush up if you are a Java developer back-end developer Java 8 features rest microservices or spring like microservices slash springboard PLA school docker and Even if you want to contribute or to our channel, you can reach us at the email edit that is there in the description So without wasting much of our time, let us see the interview questions that were shared by our friend So firstly talking about Java questions. These were the questions that were shared So how to reverse a singly linked list? This was the first question. So you have to write a program To reverse a singly linked list explain Java 8 features and few coding problem problems So Java 8 features are they have to list on all the Java 8 features and based on the features like mostly Java coding questions would be on Java stream because Coding questions were not sure only one question was shared here Explain about solid principles. So if you are an experienced guy, this is a mandatory interview question explain about solid principles So there is a separate video. I believe on our channel You can go through that video and you will get that will definitely help you out Why non static variables are not allowed inside static block So you need to know about like what are class variables? What are instance variables only then you can be able to answer it if you don't know it Please brush up. Can you create a deadlock situation without using threads? So as far as my understanding like my knowledge, we cannot create deadlock situation without using threads Or if there is a scenario, you can please comment it out in the comment section that it will help me out as well Explain the internal working of hash prep. So basically hash may works on hashing So you have to explain about all the entire thing like how hash may hash code is calculated How it is stored what will happen when we do a get what will happen if there is a hash collision? And how why you have to override equals and hash code method what benefit you will get by Overriding equals and hack short method. So these were the six questions that were shared to us like from the Java section So guys getting before getting further into the video would like to talk about the leading Hiring platform of the country that is reliable by an academy and we would be talking about the current back-end openings that are There on this platform like let us see what are the top five companies that are currently hiring a back-end development guy So the top five companies are razor pay super daily flictex more engage and animal And let us see what they're offering and what is the required skill set for them? So coming to the first company that is the razor pay So the city is 20 to 24 lakhs per annum the required skills are PHP Python Java and CPV and the second company is super daily and City see that is being offered is 20 lakhs per annum required skills are Python AWS and big data and Coming to the third company for back-end development that is flictexed and it is offering a salary of 15 to 25 lakhs per annum and the required skills are Java J2W springboard design patterns Kafka spa AWS machine learning is a place. So And the fifth company that is animal So it is offering a whooping of 15 to 20 lakhs per annum and the required skills are node.js Python MySQL MongoDB Google Cloud Firestore, etc. So if you want to get into these companies You just need to register with reliable by an academy and take the test and based on your score you will be shortlisted for the interviews and Once you get shortlisted for the interviews you will be given a special guidance by level level T level team in Tracking the interview and the entire process of this is only like the duration of this process is just one week So within one week or you will be getting the result whereas compared to other technical like other platforms other It is like the time is never ending you there is no guarantee that when the process would end But here it is just one week. So what are you waiting for to grab this golden opportunity or visit? Reliable by an academy site and register for the exam take the exam and crack your dream job And if you want to use the coupon code that is there in the description You will be getting a day extra 10% discount on the registration fee And if at all you are able to crack the interview the entire registration fee will be given back So what are you waiting for go and register for this test right now and start your dream career and Next section of questions were from rest. So these are the questions This is the world like five questions that we shared from rest What are the different HTTP methods that I have worked and in which scenario I have used what so basically? We use get put post delete Options so might be there be there might be a scenario like scenario based questions mode I have been asked here. What are idempotent method? So basically apart from post a lot of idempotent so next question is how to pass header parameters as Method input. This is a tricky question. You need to Have a good knowledge on this to pass write a sample API to upload a file This is a easy question. I could say no like if you are having experience or this is a simple question Just you need to make the configuration change Questions on different HTTP course. So it is always better better to learn about few HTTP course apart from 200 Okay, and find an internal server exception. So Like it is always good to have like for not for which is not found there are other things as it So it is always good to brush up before taking up an interview These were the questions from rest and the next section We are going to discuss about microservices or spring boot interview questions. What problems does microservices solve? So I have to explain about like what actually problem we were facing when we are using monolithic applications So even if for a small change, we have to bring down the entire application So there used to be a downtime you have to schedule. We have to send me all those things We need to do before bringing down the application now with the microservice architecture The downtime can be reduced only a particular what I can a particular service can be We can make it down and we can within a few minutes the application will come up like That is a big issue that is microservices are falling How do you maintain transactions when multiple API calls are involved? So There are different approaches it depends upon your application your application architect how they want to achieve this on what principles microservices are built upon there are in the list there is a huge list on which microservices prince like About the principles of microservices you have to at least answer five or six out of them Any idea on different API gateway platforms? So until unless you work on actual gay API gateways, so so you'll not be able to answer So please brush up on this as well. What is swagger and what all annotations of swagger have you used? Or there are like swagger is nothing but a pictorial representation of our APS. You can say we can Test our APS using swagger as well. And there are different Annotations like at the right API. There are many. So you have to tell about all those things Why is entire it running behind spring boot the reason is that it is providing out of what I can say The benefits provided well spring boot are very huge like it is reducing a huge time for developer in setting up the project It is coming up. It is having its own dependencies like what I what we can say Just by having few Dependencies of the entire application can be made up. So that is the reason like Explain what I can say remove the boilerplate code. So there we can save the time again Can you explain me the process of configuring or activator? So this is also has become a mandatory interview question This is if you are saying that you are working on spring boot then activator question is a mandatory thing like what all different HTP API is that activator will be that activator exposes that will be the continuation question of that Then the final question is explain about different spring boot annotations that you have worked So we have a separate video on this as well most of the people gets confused on spring annotations and spring boot annotations So we have a separate video on that you can go through it and will that that will definitely help you out in answering the questions So these were the questions that were shared as part of microservices or spring boot interview questions that were asked in Nagarro In the next section, we'll be talking about PLS QL questions So here are the five questions that were shared with us What is the difference between truncate and delete explain the difference between Procedure and function explain different types of joints. Can you create a trigger? How many triggers can be applied on a table? So 12 triggers can be applied as far as I know So remaining all are I think basic questions that any one who has the knowledge on DB side How would be able to answer it if you are not aware of it? please brush up before taking up an interview with Nagarro and And finally It is the interview questions with Docker. So Docker. These are the five questions Related to Docker. So what is the difference between Docker image and container? What are the common use cases of Docker? What is Docker's form? Can you run more than one application in Docker container? What is Docker entry point and only if you have hands-on experience on Docker You will be able to answer and to be honest for asking like the questions Ask for three plus year experience guys are equivalent to like asking questions to five years experience guy so We are not aware of the selection because that was not Mentioned in the interview was these were the questions So here is a mail that here is a complete mail that we have received So high team has recommended like just you can brush up the questions again Like different topics like Java 8 features rest questions microservices spring boot interview questions plsql interview questions docker interview questions So the questions we have already gone through so this would that this was This was the mail that we have received from our subscriber friend And if you want to contribute you can reach us at the email ID in the description And you can use our affiliate amazon affiliation link as well Which is there in the description to get some extra benefit Like extra discount that are on selected products that you are getting some extra 2-3% discount So you can make use of that as well And if you are on our channel for the first time and wondering who are we and what we do So we are basically bunch of software engineers who attend interviews with different MNCs and share our real-time interview experiences through these videos And apart from that we also share our Subscriber friends interview experience as well So this is one among that like our subscriber has like subscriber friend has sent us an email regarding his interview experience With nagaro and we have explained in this video.
