Background : DeepThought Edutech Ventures was hiring for this company 12th Wonder. The first round was relatively easy but I chose to go the extra mile & impress the recruiters by adding relationships between data models & folder structure. It was also asked of us : to create API documentation & according to my skill-level then, I think I managed it well. I created the YAML file & got to work it with my Express API. I deployed it on render. Recently, I removed it from deployment because I exhausted the free-quota.

The Task : We were asked to create a backend api for an imaginary organisation where people can create announcements & link events with those announcements. Also, room for innovation was given so that the recruiters could know how far a guy can stretch it.

What I did : Thanks to my learning from Udemy, I knew the basics of API creation & testing with postman. The fun part was to add bells and whistles to the Basic API routes, controllers & middlewares. For this, I added relationships between the data-models. You can see in the Github link which I have attached. Also, I worked a lot on handling edge cases & errors.

https://github.com/mkpgtr/DeepThought_NudgeAPI/blob/master/routes/subCategoryRoutes.js (look at line 13)

I added code that will validate parent-child records & store data in proper format. I had added other stuff like this in the image Upload API of this project also.

After this project, there was interview on this project. Here I was asked to just open the code which I had submitted. My project was good but the interviewer told that : I had to convert this whole code into MYSQL code. So, in the next round I brought forth the MYSQL version.

Because I did extra things from my side in Round One, it was scary for me to convert those mongodb relations into MYSQL foreign-key like relations due to the fact that : I never worked with mysql library for Node JS as extensively as I worked with in this project. 

There were lots of cases in this project, where I was confused how to approach the problem. Like linking values from one table to another & then generating another table by using values from some other table.

The loops I have written in this file : https://github.com/mkpgtr/NudgeAPI_MYSQL/blob/master/routes/eventRoutes.js 

were worth the hard-work. I did not know I could do it but somehow I was able to manage it. In other files also, you can see that I have tried to work out solutions someway or other. & this is not chatGPT code. 

I wrote this code from first-principles & from the understanding which I had regarding : how MYSQL works (7months ago).

When I finished the task, I was pretty sure that the interviewer would love this. & so it happened. I was asked to show this code in the live round. There, my understanding was tested about how to hit routes & how JWT works & all. I was also asked about middlewares. 

Finally, I was asked to build the frontend for this API. So in the next round, I had to present the frontend for this API. I created the frontend in React.

It was straight forward API consuming & I was quite burnt out by now because of doing this one project. I added the feature where database changes would be reflected in the dropdown. linked the dropdown options to database records. also added pagination feature. image upload was done via axios. & other stuff like that. I took the pagination logic from chatGPT & told the interviewer that this logic was taken from chatGPT.

Until now, I had been interviewed by the software developer of DeepThought..But this time the interviewer was the tech-lead of 12th Wonder itself. 

I was asked to write MYSQL queries. I had implemented a feature where, if a parent record was deleted then child record would also get deleted. I did this via On Cascade Delete option in mysql admin dashboard.

I also showed the interviewer how every piece of code is working & related to each other. The interviewer was very impressed & he asked me to learn about caching. After 6 hours, I implemented that caching feature using node cache library & I learnt about how caching works in nodejs. It was a nice interview experience.

The HR round happened before the technical rounds. DeepThought has an awesome recruitment process. It was of seven days observation period. From 5PM to 9PM we had to attend a Zoom link video call & do group discussion & observe people already working in different companies in the Zoom Rooms. I passed that observation period within four days.

Also, we had to write reflections about what we learnt each day on the zoom link. So overall, this was the most transparent & effecient HR rounds I have ever come across while giving interviews.

It was technically of 960 minutes : 4 hours for 4 days
