The most comprehensive bank Interview Answer Review tooling available online.

I have more than a decade experience working as customer success engineer in which I tried my best to solve a customers problem. During this course I have interacted with several product engineering and product managers and worked very closely with them. I aspired to be a product manager because I wanted to solve a customers problem even before they realized it by understanding their use case, feature requirement, motivation to use a product. I found this role to be very challenging and exciting as I have to think more like a customer than an engineer trying to solve a problem, identify their persona and how I can ease their day to day job. So when I eventually got an opportunity in my past organization to work as a product manager I took it.

Usually in one's career sometimes they are asked to work on somehting which they are not motivated to work for and it's not as challenging as other projects. Then I usually try to align the work they doing to not what I or compnay would gain form it rather what is their benefits from it. Also, at teh same time acknowledging the downsides of that project like it;s legacy systems and may not give them greenfield field projects opportunities for you but they are bread and butter and their continuity is important and  usually these projects generate better impact which is were performance reviews are very helpful 

Assuming we are talking here about the experience of flight arrivals/departure from a specific airport.  Few key data points to be considered while designing this experience:

a. Weather of the specific area

b. Availability of runway to land or take-off

c. proper functioning of the communication devices between pilot and ATC

d. In air assistance to the pilots

e. Pilot to be able to smoothly report air/weather conditions back to a central system from where then it can be relayed to other flights passing through the same area.

While all other use cases are seem to be handled, e is the one where I feel there is a lot more that can be worked on referencing the SIA incident happened recently.

 Let's design a central system where pilots should be able to send real time weather climatic feeds. It could be a server with high computing capabilities as the data from this server will then need to be relayed to multiple other flights passing through the area. One can think of this server as a self sufficient system with all automation processes running inside it. The way it will work is:

a. Capture all the feeds from the flights in air

b. it should have access to data of all the flights of specific areas, ofcourse there will be mutiple such system deployed for load balancing, DR, security and other privacy reasons

c. All these servers should be able to communicate with each other as well

d. Any critical (Red/yellow) information to be relayed to the flights passing specific Area.

e. This should be a next-gen system which should pro-actively warns pilot/flight if any specific area has seen critical incident happening or likely hood of Air incidents when passing through the area.

f. The system should be able to help pilot navigate through turbulance if already caught like what height, speed and angle to Manov our the flight to come out of the turbulance.

g. Should be able to send SOS signals to the nearby airports/flights if the system has identified that the flight will need emergency landing assistance.

Designing such system will require extensive Infrastructure as well as thorough testing and should be piloted first with small amount of flights in the region with less air traffic and then a slow roll out per region should be an ideal way with catching and fixing bugs along the way.

Success Metrics:

North star: Accurate predictions

Number of times it relayed critical weather alert to the pilot also capturing false positives

Number of times it triggered SOS, capturing false positives

How many airports have adopted this

With scale are we seeing drop in accuracy

How many flights a single server can successfully monitor

Time it takes to process information and then send it back to pilots

Availability of the system itself

Pricing:

Given the monster system to be designed, this is likely to be pricier as the infrastructure it will need and software that need to scale with flights, people travelling across the board etc. At a very high estimate a single server may cost from 100K to 300K

In my last role I had to make a UX decision about the product that will balance functionality for the user without compromising performance. After testing a few options and validating it with internal stakeholders I released the updated UX, but then the CEO (who was a heavy user of the product) was against that change. I saw down with him and explained my reasoning and the process that I took to validate the solution, and gave him the option to try it himself on an early version. Once he saw the big picture he agreed that my solution was the right approach, but asked that next time I will consult with him before releasing changes like this. 

I would separate the vending machine into different components: display for product selection. Storage for keeping the inventory of the products to sell. Delivery mechanism to hand out the products and the payments interface. I would include elements to adjust the user interface to the client. For example the customer can be a child, an adult or a person with disabilities. I would place sensors to detect the customer height and adjust the user interface height. The vending machine will be connected to services sending events when a product is getting low in inventory. The payments component would be able to process different payment types. And the delivery mechanism would select a product from inventory and deliver it to the client. The products will be shown as picture in a display rather than directly shown the product through a crystal that way the inventory can be managed efficiently without having to care for the display of the products.
