I got my dream internship after watching this video! Thanks a ton! ♥♥♥♥♥

I love that he's actively using his environment in the interview, when he's going through users, you can hear police cars outside and he throws a curve ball user group out: policemen. From my understanding, it's good to have some outside the box answers when enumerating different users and problems - great job

The interviewee is so smart, he is using framework, but most amazing is how he answered the interviewer’s questions. And the interviewer asked several really good questions. A great mock interview.

One of the the point Sushant suggested that AI would read all the messages and based on it, it would give suggestions. One of the KPI he could've added was, number of times a person click on the nudget so he can track the "No. of suggestions asked by person and offered by AI." This might help to track the success metrics of the AI.

Emoji interpreter and abbreviation/slang translator would be something my grandma actually asked me about! I'd add them as a key FR for the elderly.

That was fantastic! Loved the structure and easy flow of the interviewee! Clear and concise!

how about analyzing quality of conversations as a metric, whenever you remove friction in a flow - generally the quality of the metrics go down?

I'm very impressed that he starts with punchy clarifying questions across goals and customer segment.

Can we have some sessions on product teardown for B2B products with complex workflows so we can understand how PMs thought process ?

These mock interviews really help me understand how to handle these questions. Even I know the solution but handling the question in right manner matters a lot. I recently cracked one of my product manager interview which was on problem solving. My question was somewhat similar to your Flipkart problem solving mock interview, so thank you so much for this informative content. You guys are doing really good work.. keep it up. 👏👏👏

This kid is brilliant. Breaking down the problem systematically/structured thinking and speaking was top notch

do you have pointers on how to answer KPIs for the success of a feature , like the one asked here, number of messages sent or received may not be a good indicator .

A good interview. He expertly fielded the questions like a pro. Just one point: if there are any features that are being introduced and if one is not too sure of the reception, then TEST. Always have some sort of beta testing built-in, especially when dealing with large-scale customer-facing products. The responses will be a litmus test for the product enhancements being proposed.

Problem statement is to improve User Engagement so rather than going into ideating a new feature to increase time spent on WhatsApp, focus should be is there scope to increase usage of existing features like a. Increasing number of chat messages b. Increasing number of video calls c. Increasing number of voice calls d. Increasing number of status updates Such questions could have been asked whether we want to improve existing features for any particular target segment to increase usage, also in which age group or gender user engagement has been observed to be low. There can be usability issues with existing features which can be improved to enhance user experience

I think focusing on UX for the elderly is important. In China for example, where the generation didn't learn how to type (similarly in the west), they draw out characters with their fingers on the screen which translates to text. This is one way they have focused on this problem.

Half way into the video, engaging elderly people on WhatsApp. First up, I really appreciate the candidate for thinking from the heart instead of the brain, getting into the persona/emotional side of people and delivering a delightful User experience. I have one question, regarding the text assist, expressing/Understanding the messages. WhatsApp already have a voice message option, Wouldn't that solve all of the above mentioned problems. However I still like your idea of synchronizing event onto a calendar & sending timely reminders. Overall pretty impressive thoughts. Thanks!

great, practise interview. Thank you for uploading it. Wanted to share a few thoughts which echo some of the earlier comments. An on machine-based ML-powered assistant to help elderly and other segments of users understand and reply to messages is great but would it be better to provide simpler ideas such as collating all the previous unread messages and providing a contextual summary either in words or audio (of your preferred language) to the user? This summary could also tie in contextually with earlier messages and take into account the relationship between the sender and receiver (another additional parameter for the app to collect with user consent). Within this brief, it could also highlight events/reminders/other important keypoints and suggest the tone of brief, similar to what Gmail does? At the end, it could provide suggestions for replies.

These videos are really helpful, can you add Scrum and Agile project manager videos?
