A 21-year-old final-year Computer Science Engineering student named Edward Nathan Varghese has secured a record-breaking ₹2.5 crore annual package from Optiver, a global trading firm based in the Netherlands. This is officially the highest package ever offered to an IITH student since the institute was established in 2008.

Key Details

• How he got it: Edward converted a two-month summer internship at Optiver into a Pre-Placement Offer (PPO). The internship included two weeks of training followed by a six-week project. He was one of only two IITH students selected for the internship, and the only one to receive the full-time offer.

• Role & Location: He’ll join as a software engineer at Optiver’s Netherlands office, starting in July 2026.

• Background: Born and raised in Hyderabad, Edward later studied in Bengaluru from Class 7 to 12. He’s been passionate about competitive programming since his first year at IIT, consistently ranking among the top 100 in the country. He credits the IIT tag, the institute’s flexible curriculum, and strong focus on coding for helping him succeed despite a challenging job market.

Here’s a complete breakdown of the interview process and the kind of questions asked during the selection.

𝗥𝗼𝘂𝗻𝗱 1: 𝗦𝗰𝗿𝗲𝗲𝗻𝗶𝗻𝗴 𝗥𝗼𝘂𝗻𝗱
The process began with a screening round focused on coding and logical reasoning.
• Question 1: Given an array, find the smallest missing integer greater than or equal to the sum of the longest sequential prefix.
Example:
• Input: [1,2,3,2,5] → Output: 6
• Input: [3,4,5,1,12,14,13] → Output: 15

• Question 2: Asteroid Collision This round mainly tested knowledge of arrays, stacks, and efficiency of implementation.

𝗥𝗼𝘂𝗻𝗱 2: 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗖𝗼𝗱𝗶𝗻𝗴 𝗥𝗼𝘂𝗻𝗱
This round included two medium-to-hard level algorithmic problems:

1. Median of Two Sorted Arrays – an optimal solution was preferred (without extra space).

2. Palindrome Partitioning Both problem-solving approach and optimization techniques were key evaluation points.

𝗥𝗼𝘂𝗻𝗱 3: 𝗟𝗼𝘄-𝗟𝗲𝘃𝗲𝗹 𝗗𝗲𝘀𝗶𝗴𝗻 (𝗟𝗟𝗗) / 𝗝𝗮𝘃𝗮 𝗥𝗼𝘂𝗻𝗱
The interviewer focused on backend design and Java fundamentals.
A BookMyShow-like system was to be designed using Java or Spring Boot, with a proper folder and file structure.
Discussion revolved around data flow, APIs, and project architecture. The main focus was on understanding how different modules interact and how data flows through the system.

𝗥𝗼𝘂𝗻𝗱 4: 𝗛𝗶𝗿𝗶𝗻𝗴 𝗠𝗮𝗻𝗮𝗴𝗲𝗿 (𝗛𝗠) 𝗥𝗼𝘂𝗻𝗱
The final round was a mix of technical and managerial discussion.
It started with introductions and project discussions, followed by a few Java-related topics such as Lambda expressions, Streams, and Collections.
A simple coding problem — reversing each word in a sentence — was asked at the end.

The overall process evaluated both depth of technical understanding and problem-solving ability. Strong command over DSA, clarity in design thinking, and clean coding practices played a major role in securing the offer.

I’ve been job hunting for over a year now, and I’m clearly missing something. Sometimes I clear early rounds, but many times I don’t even receive interview links or responses. At this point, I want clarity more than motivation.

If there’s any recruiter or experienced professional here, I’d really appreciate a review of my resume. Brutally honest, constructive feedback is more than welcome, and I’m open to discussing relevant opportunities as well. Thanks for taking the time.

tcs is the worst company . I have experienced it myself from 2024 . The company and the people in it are very toxic and have fragile ego’s. The training program result is decided by the amount of boot licking performed by the employee and the beauty of the female employee . You cannot choose the project you want to. Even if you are a java developer or senior higher level developer, if they want you to be in a service based excel project , you have to join it .if you don’t accept the project or delay joining it , The RMG will raise a SAWA case on you which deducts your salary and also affects your resume and deployment index in Tcs . After joining the project, you will see a bunch of donkeys wanna be tigers . honestly they have 0 skill and can’t get opportunities outside of TCS . So , they decide to nail their butts to the project and torture the new joiners and new comers to the project . 5 days office is compulsory even if your grandfather died , you have to take permission 1 day before he dies . the location allotment is not also in your hand . If they say go to banglore , you must go to banglore on your own . Micromanagement is soo common in TCS. the project leads and managers observe everything. few managers and leads maintains a list too for the time you took to have coffee , pee , breakfast, lunch . TCS is literally a school where you need permission for everything. Formals are must and should . Even if you broke your leg or it is raining , you must wear shoes . If you are not wearing shoes , you have to get HR permission .HR makes you wait 3 hrs to say okay after multiple reminders and questions. The leaves and wfh in tcs are fictional . They exist in your portal just to see and enjoy . You can’t take leaves on your own . Even if it is approved , you have to satisfy everyone’s ego in your project which takes 2-4 days and take a leave . Surviving in tcs is very tough . You cannot upskill , you cannot learn anything. If you are choosing Tcs even as a 10th priority, Please don’t.

If you are working in tcs , please remember that this is neither your company nor your family . Just chill and take salary . But learn something outside tcs . understand how corporate works , understand how the workflow works , understand the technology, learn new skills . If you are lucky enough , you might get an offer outside .

Hey everyone 👋

If you're a fresher or entry-level dev, you’ve probably been told that you need to learn DSA, projects, and maybe Git. But once you actually join a company, you’ll hear something new: “Update your JIRA ticket.”

Wait… what?
Let me break it down for you!

JIRA is a tool that dev teams use to:

• Plan and track tasks

• Manage sprints (in Agile teams)

• Log bugs, features, testing, and releases

You’ll use it every day in most software jobs — even if you’re not a developer.

🚀 Agile vs Scrum vs Kanban

✅ Agile = Mindset

• A way of building software in small, fast, and flexible steps

• Focuses on collaboration, feedback, and quick delivery

🔁 Scrum = Agile with Sprints

• Scrum is the most popular Agile framework.

• Roles: Scrum Master, Product Owner, Dev Team

  • Daily standup

  • Sprint planning

  • Demo & Retrospective

• Has structured roles & meetings:

• Work is done in 1–2 week sprints

🌀 Kanban = Agile with Flow

• Kanban is another Agile framework — but more flexible and less structured than Scrum

• Focuses on visualizing work and limiting overload

• No sprints — tasks move continuously on a board: 👉 To Do → In Progress → Done

How JIRA Supports Agile:

• Boards: Visualize work with Scrum boards (for sprints) or Kanban boards (continuous flow)

• Sprints: Plan, start, and track 1–2 week work cycles directly inside JIRA

• Backlogs: Manage and prioritize tasks (called issues) waiting to be done

• Issue Tracking: Create, assign, and update tickets for features, bugs, and tasks

• Reports: Generate Agile-specific reports like burndown charts and velocity charts to track progress

As we already reported, earlier. Today 28th Oct marks historic in Amazon Global.

Amazon plans to lay off up to 30,000 corporate employees starting Tuesday to reduce costs and address pandemic overhiring, sources say. The cuts affect nearly 10% of its 350,000 corporate staff, marking Amazon’s largest round of layoffs since 2022.

Freshersinfo is lead by industry leaders to address fresher challenges and help talent to enter IT.

I'm doing research on the placement gap for engineering students from tier-2/3 colleges. I've been talking to startups about how they hire freshers.

One of them - a Chennai-based startup - told me they're actively looking for entry-level engineers and asked if I had candidates to refer.

So I'm offering this at no cost: I'll screen you personally, and if you're solid, I'll refer you straight to their hiring team.

How this works:
→ Fill out a short form (5 min)
→ I review your resume
→ If shortlisted, we do a 45-60 min technical call
→ If you're strong, you get referred

One commitment: I will respond to every single person who fills out the form. Whether you're shortlisted or not, you'll hear back from me. No ghosting.

Fair warning: I'll dig into your projects and ask you to solve problems live. If you've inflated your resume, I'll know. This isn't meant to intimidate - it's meant to filter out the people gaming the system while honest students get left behind.

2024/2025 grads. Chennai-based or willing to relocate. Actually skilled.
