Walmart Interview Experience Aug-2020 (On-Campus)

Walmart visited our campus in August 2020. The complete interview process was virtual. It was a 5 round process.

Round 1 (duration 90 minutes): The first round was unsupervised round on HackerEarth. It had 25 MCQ’s (25 marks) and 1 Coding question(25 marks).

1. MCQ’s: MCQ’s included Computer Network (CN), Operating System (OS), DBMS, and aptitude questions. MCQ’s were easy and medium level.
2. Coding Question: The coding question was a medium-difficult level question. This question was the decider for shortlisting (since MCQs were easy).
3. Question: Fake Palindrome: Return the number of Fake Palindrome substring in a string, where Fake Palindrome is a string whose anagram is a palindrome.

Test Case 1:

Input: ABAB 
Output:7    
Explanation: (“A”,”B”,”A”,”B”,”ABA”,”BAB”,”ABAB”)

Test Case 2:

Input: AAA 
Output: 6   
Explanation: (“A”,”A”,”A”,”AA”,”AA”,”AAA”)  

Many students got partial marks for this question using a map for every substring. I had used bit masking concept for solving this question (Maybe overkill for this question, but it cleared all test cases)

23 students were selected for the next round.

Round 2 (duration 45-60 minutes): Second round was a** technical round** over Zoom Meetings. The interviewer asked about CN, OS, and DS/Algo.

1. Layers
2. Virtual Memory
3. Segmentation
4. Process and Threads
5. Kernel
6. Protocols (HTTP, TELNET, FTP)
7. VPN
8. Routing
9. Types of Binary Trees
10. JAVA (OOPS concept, Exceptions, etc.)
11. Coding Question (Greedy and Dynamic Programming question)

These were some questions he asked.

The coding question was very easy compared to the first round. He wanted to know the approach and intuition for every solution. There were some trick questions in the interview like given post-order, design a tree.

15 students were selected for the next round.

Round 3 (Duration 60 minutes): Third Round was a technical round over a Zoom Meeting. This was DS/Algo round. I was asked to code and execute questions on IDE.

1. Longest Increasing Subsequence.
2. Find a continuous subarray whose sum is equal to target sum. I solved the question with iterative approach(O(n^2)) and map approach(O(n)).
3. Iteratively find the postorder of a tree (stack approach).

12 students were shortlisted.

Round 4(Duration 30-45 minutes): Fourth Round was a Managerial round.

1. I was asked about my internship, what did I learn there, and what obstacles I faced during the internship.
2. Interviewer asked about the project. Also, asked some software engineering question like the Waterfall Model.
3. What is your approach to learning new technology?
4. Why do you want to join Walmart and how are you fit for the job?

These were some of the questions asked during my interview.

Round 5(Duration 20-30 minutes): Fifth Round was HR round.

1. Tell me about yourself.
2. What do you know about Walmart?
3. Are you interested in Higher Studies?
4. How do you adapt and overcome a difficult situation?
5. Your CGPA is relatively less, why so?

Citrix Bugs Allow Unauthenticated Code Injection, Data Theft

Multiple vulnerabilities in the Citrix Application Delivery Controller (ADC) and Gateway would allow code injection, information disclosure and denial of service, the networking vendor announced Tuesday. Four of the bugs are exploitable by an unauthenticated, remote attacker.

The Citrix products (formerly known as NetScaler ADC and Gateway) are used for application-aware traffic management and secure remote access, respectively, and are installed in at least 80,000 companies in 158 countries, according to a December assessment from Positive Technologies.

Other flaws announced Tuesday also affect Citrix SD-WAN WANOP appliances, models 4000-WO, 4100-WO, 5000-WO and 5100-WO.

Attacks on the management interface of the products could result in system compromise by an unauthenticated user on the management network; or system compromise through cross-site scripting (XSS). Attackers could also create a download link for the device which, if downloaded and then executed by an unauthenticated user on the management network, could result in the compromise of a local computer.

“Customers who have configured their systems in accordance with Citrix recommendations [i.e., to have this interface separated from the network and protected by a firewall] have significantly reduced their risk from attacks to the management interface,” according to the vendor.

Threat actors could also mount attacks on Virtual IPs (VIPs). VIPs, among other things, are used to provide users with a unique IP address for communicating with network resources for applications that do not allow multiple connections or users from the same IP address.

The VIP attacks include denial of service against either the Gateway or Authentication virtual servers by an unauthenticated user; or remote port scanning of the internal network by an authenticated Citrix Gateway user.

“Attackers can only discern whether a TLS connection is possible with the port and cannot communicate further with the end devices,” according to the critical Citrix advisory. “Customers who have not enabled either the Gateway or Authentication virtual servers are not at risk from attacks that are applicable to those servers. Other virtual servers e.g. load balancing and content switching virtual servers are not affected by these issues.”

A final vulnerability has been found in Citrix Gateway Plug-in for Linux that would allow a local logged-on user of a Linux system with that plug-in installed to elevate their privileges to an administrator account on that computer, the company said.

ZS Associates Off-Campus Interview Experience 2020 | DAA Profile

ZS Associates is a consulting and professional services firm focusing on consulting, software, and technology, headquartered in Evanston, Illinois that provides services for clients in private equity, healthcare, and technology.

ZS has 3 offices in India namely New Delhi(Gurgaon), Pune and Banglore.

ZS often visits colleges across the country to hire freshers as well as experience professionals specially Engineers, MBA graduates etc.

**I applied through their online careers portal and was fortunate enough to get the test link. **(The chances of getting the test link through online portal is very less).

**Online Round: **The test comprised of MCQ’s based on Quantitative and Qualitative Ability, Mental Ability, Logical Reasoning, English Comprehension and the likes of questions asked in CAT. There were around 45 questions and the time allotted was around 90 mins.

After almost 6 months, I received the response from ZS, that I have cleared the test and they wish to start with the Interview Process. It started with a Telephonic Interview.

**Telephonic Interview: **Basic questions were asked in phone call. My experience, my motivation to join ZS, What do you know about ZS. Later, the interviewer asked me a Guessestimate question to which I was given 5 minutes to think and answer. Keep yourself ready with Guessestimates and puzzles, as they test your ability to solve a question quickly.

After the Telephonic Interview, I was asked to wait for the response from the Team and I was selected for the next round.

**The next round was a Case Study Round. **

**Case Study Round: **You are given a case study of an imaginary firm/company. You need to study the case thoroughly and answer the questions that follow. This round tests your solving ability. It was not an easy case study. I was given 1 hour to study the case and was connected to an interviewer to present my answers.

I was able to solve almost all the questions which were asked in the study. Then, the interviewer started asking me questions, related to puzzles. I am not able to recall the questions but I was asked 2 puzzles both of which were not at all easy. Then, I was asked another Guessestimate, for which I was to think of the approach and reach the solution while talking to the interviewer.

This round was quite an important round, because they asked back to back questions to check your mental state and solving ability by introducing a little stress environment. You just have to be calm and not lose your tempo. The interviewer are very gentle and keep helping you during the Interview.

I was shortlisted for next round.

TCS Digital Interview Experience (Off-Campus)

I had first given TCS NQT after which students with top scores were given a chance to give another assessment – TCS Digital. The suspense here was after getting a call for an interview we didn’t know whether we were being considered for Digital or Ninja profile.

Round 1: It was a technical round lasted about 40 mins. Two Interviewers. Though most of the interviewers ask questions about DSA and related subjects to CSE to freshers that were not the case with me.

The first question they asked me was:

” Tell us about yourself…”:

Though a very general question but the answer to it is very tricky. Your answer decides what they gonna ask next. The ball is in your court here. If you give an interesting and thoughtful answer they’ll ask you about the same things you mentioned.

My Answer: “Basic Introduction. I’m a Backend Developer and I’ve worked on some live projects… I work on Python | Django, GIT, AWS…” Now for a fresher its a good start. They started to ask me questions related to the work I’ve done, the technologies I’ve used, how I started, and my future goals…

For some, such a twist might not be beneficial but I consider myself fortunate enough to have this.

Round 2: It was an HR Round. This was really one of the best discussions I’ve ever had. We talked about almost everything from the Abrogation of Article 372 by Modi Government to Paytm’s business model to Blockchains and Cryptocurrency and so on… Well, it would have been easy if you read a lot and have knowledge of all these things…

Earlier I thought that it would be easy to crack the interview based on the given JD and my technical knowledge. But it really got tricky in the non-technical discussion when we were sharing insights and opinions on the ongoing hot topics. I never thought that such subject knowledge can be sometimes useful even when you are being interviewed for a full technical profile. Really an amazing and enriching experience throughout the process.

Because if you try to fluke the topic, the interviewer may catch you and ask more questions on the same. This happened with many students on that day. Students fluked the essay topic, further, the interview asked them to describe what you have written in the essay in short.

And Finally, He said “ I am done with the interview, Do you have any questions?”

I asked him regarding the Wipro Turbo Challenge.

He replied that Wipro is working on it, you will receive the updates regarding the same through mail.
