Xetech Software Developer Trainee Interview Questions, Process, and Tips

The company came on campus, and it was the very first round in which it was not a group discussion, more it was like an individual interview within a group of 10 people of my college, the interviewer asked question on Polymorphism, Inheritance and difference between class and structure and told everyone to not to speak same answer as the groupmate it was all live and was proctored.
I was the only Person out of sixty one students who were shortlisted for face to face interview in Noida add the company's office itself I reached there add two in the noon There was no receptionist I waited for like 57 minutes on the sofa I knocked the gate nobody answered it again knocked the gate there was a developer standing over I asked him to come out and I had a word with him and what the statement he gave me I was in shock he asked me why are you here and for what purpose you are here I was like bro is this for real I told him I had an interview scheduled and I came all the way from a particular place which is 280 kilometers one side from their office and I started 4 in the morning.

They gave me a coding question paper in which there were two questions number one was reverse a string and input sample input was Helo and we have to reverse that and the next question was of matrix in which the question was there is a matrix of M Cross N Rows you have to spiral traverse it in clockwise direction and output the elements in one day array form this was the question so I had to solve this I solved both the questions but the 1st 1 was absolutely easy I cleared it very easily and the second question it was little bit tricky and it was of medium level so I attempted it and 15 to 20% I made some logic and gave the paper to the HR that I am done with the paper you can give it to the concerned developer and After my paper got checked the developer came It was that developer only Whom I have mentioned in the very first paras he was from Bihar he came to me he told me Explain both the programs I explained him the first one very easily and I explained him the 2nd one program's approach as welI I did knew that it was not absolutely right but yeah I told him the approach that I used so he told me to explain me the very first program which was reversing of string without using the logic which I used the logic that I used was of slicing he said me that he told me that I don't have to use this logic And neither I have to use a direct function he told me you have to solve this program by a logic in which you don't have to define a new variable I was like I asked him questions back and forth for 5 to 7 minutes we had a discussion and I gave him the code in python he said no so I gave him the code in C++, in C++ when I used the loop so I have to initialize i that means I have initialized a new variable I gave him the paper I made my hands up I was like no sir I'm not able to do it if you can do it would be very appreciable so he took the pen and wrote the code and the funniest thing I found about that when he wrote the entire code he defined 3 new variables and I was like you told me not to do that and you're doing it by yourself and I asked the interviewer very politely sir you have defined 3 new variables so he told me no no no the question that I wanted to ask you that there should be low space complexity I was like what the heck bro he didn't ask me this question and to defend his answer he told me that we can erase these things these 3 things I was like if I would have done that you weren't allowing me to erase that and if you did then you can erase that bravo!!! well done this entire process was completed in less than 5 minutes then the HR came she told me we will intimate me the result through my WhatsApp but I asked her again she told me we will intimate you through WhatsApp and when I came out of the office I knew it because they didn't have my WhatsApp number I knew it so moral of the story is I wasted my 20 hours of single day because I traveled back to the same place from where I started I lost my 20 hours just for the sake of 5 minute interview and how on Earth you can judge a software developer trainee interviewe in less than 5 minutes.
