“Would you join us for a trek next week? It’s organized by TCS Maitree” — came a subtle voice while I was busy analyzing what went wrong with a mission-critical web application.

I turned to see Gaurav, my colleague, with his typical North Indian smile. “I’ll check the mail”, I said and turned to fix that application that had already resulted in 15 calls from customers asking for turnaround time.

Another 20 minutes and the application was up and running! When customers and clients are happy, we have some time to kill. I turned to find Gaurav on his desk only to see a small gathering already. …

I have always wanted to study abroad. While working on my professional goals back in 2015, I figured that an MBA would be the perfect next step to springboard my career. I saw this as an opportunity to experience a new culture.

After settling on The United States of America as my study destination, and after securing admission to one of the Top 40 b-schools in the country, I was exploring ways to finance my education. The worst part about super-high exchange rates between the US and India is that a lump sum money in my home country was peanuts here. …

What is Facebook’s Product Sense interview?

Facebook product managers own and manage global-scale products. They are navigating constant ambiguity when it comes to problem-solving. They think about their product 24x7 to identify the most pressing problems for its users, the most impactful solutions, and how the product ties back to Facebook’s strategy.

It’s not possible to assess every aspect of that process during an interview.

So, the product sense interview serves as a proxy. Essentially, this interview is all about how you think about user problems at scale, and turn that into a concrete product(s).

Any and every question that might require you to think about users is, in some way, a product sense question. …

What Is AutoComplete?

Autocomplete is the feature by which a system (typically a search engine) understands what you intend to write.

The world is in the middle of a crisis for at least 3 months now. Several businesses collapsed, unemployment rates are at an all-time high and nobody knows when this situation is going to be better.

But the pandemic has proven to be a silver lining for a few businesses. We all have already heard about how Zoom shot to fame among consumers. Netflix added 15 million subscribers in a quarter, more than double the 7.2 million that was projected.

With such success comes risk. Such exorbitant success is a ripe ground for fraudsters to game the systems. We, at TeleSign, a digital identity and programmable communications company, tried to analyze the trend in our North American business, and this is what we noticed. …

Restaurants have been one of the most frequented places until even a couple of years ago. Celebrating the first job, an engagement, a big bonus, marriage anniversary — all of these had one thing in common, a restaurant.

Recently, with the surge of food delivery applications, restaurants have been observing an ever decreasing traffic. Joe Hargrave, co-owner of Tacolicious, mentioned that the number of lunch customers has decreased by 35 percent although revenue rose by 8 percent. …

You have a great idea. But you need to validate the product market fit before you move forward with investing in building the first iteration of the product. This post explains one of the many ways you can do that.

Product market fit isn’t a new concept. Yet, it’s one of the hardest things to achieve. You come up with a great concept, maybe something that either doesn’t exist or is a 10x iteration on an existing product. …

I googled “credit score” and it threw 770 million results towards me. The internet is full of content ranging from experiences when someone with sub-prime credit had to pay exorbitant interest rates on a mortgage to guides on how to improve credit score. But what makes a credit score so important to lenders?

What’s A Credit Score?

A credit score lets the lenders have a peek at our financial behavior. From answering “how responsible are we with money” to help predict our chances at defaulting, a credit report provides valuable information the reporting agencies have gathered over the years from banks and credit unions. But what about the population that doesn’t have access to a bank account? Even worse, what about those who don’t use an account in spite of having one? …
