Situación laboral de la población inmigrante en Andalucía

As part of my Practice School 2 I interned with Flipkart in Bangalore. I arrived in Bangalore a week before the internship date to start looking for accommodation near the office and found a PG at Marathali which was around 5 kilometers from my office. The first thing which catches your attention is the amazing office architecture. Since I had already worked in a startup milieu before joining BITS I was expecting regular office cubicles with perhaps some frills but when I entered the office I was bedazzled by its exquisiteness, every floor had its own theme with marvelous conference rooms, delightful common areas and comfortable seating. Every small thing has been taken care of with utmost attention, from the placement of reprographics to the arrangement of the desks. The first day was a little overwhelming with a lot of people trying to befriend me and asking questions to which I repeated my bio-data like the first day of

184 college. As a fledgling intern my greatest endeavor was to lean the tools and technologies being used at Flipkart. Since my prior experience was in .Net technologies I was not so comfortable in working with Java and other open source related tools. This continued for a couple of days while my mentor, manager and team members’ brain stormed on my project. I was usually part of the discussion physically but couldn’t really participate since I wasn’t aware of the domain, the tools and the technologies being used. For the most part of the first two months I was participating in requirement meetings, design discussions and skill development tutorials without writing any code. At one point, I remember consulting my mentor on the fact that whether I would be writing any code during the internship to which he said once you start you’ll be writing code till your last day – he was correct. Once the development started all my office hours were spent writing code & I was able to finish my project with great help from my mentor, manager and team members. Looking back, I feel it was a right decision to choose Flipkart, Bangalore as the PS-2 destination. It was the first time I was living alone outside my home (Pilani was always a home to me as well), I learnt a lot about work as well as about life. My fellow interns were friendly, my team was affable and my mentor was empathetic. Initially there was not much work but when everything was finalized (which took around 2 months) I was given interesting work. Commuting on weekdays is always an issue in Bangalore while weekends were amazing with my friends & colleagues. I did not want to work in Bangalore hence did not apply for a PPO. My journey with Flipkart has been an amazing experience and it would be a fond memory for the rest of my life.

Overall work has been satisfying. The interns were allotted into mainly two teams. One is “Seller Platform” while the other is the “CustomerService”. My team is Customer-Service where all the issues from the customer both in preorder and postorder are handled. Various sub-teams are present which work on telephony, machine-learning , NLP are present. Learning and work-culture is very good. Interaction within the team is lively and you can approach to anyone in your team for queries. I have learned how the whole customer call centre works in an e-commerce platform, and also the whole telephony procedure. (like the CTI - Computer Telephony Integration) Here, there is a chance to learn a lot of new concepts and there are no restrictions in code structure, but many of the teams use Java only. The timings are flexible and you can work according to the timings of your team. The work stress for interns is a bit less but for full timers, they are tend to work on weekends also, but that even depends on the team. You are allowed to work on the Prod environment directly, this kind of exposure will not be obtained in any other company. you are allowed to work on many topics of your interest, apart from you work. Various learning sessions are also conducted by the company for the academic improvement of the employees, where interns can also attend them. Overall, very good working environment and best place to learn a lot of new concepts.

Project involved analyzing customer complaints by mining frequently occurring patterns in complaints, grouping complaints based on issue or other parameters, providing metrics of number of times team’s resources are used by clients and call center agents. To handle huge size of data(3050GB), parallel variants of algorithms were used. Along with solving the problem, picked up elegant coding styles in JAVA like Google Guice and caching when required(InMemory vs Centralised).Technology Stack: Dropwizard, Apache Spark, Spark Mlib, Spark SQL, Codehale Metrics. How did I acquire the skills? I went through

185 documentation and online resources while picking up concepts. If this does not work, “ask” team members/devchatter(ministack overflow at Flipkart)/walk up to anyone and discuss your problem. It’s as simple as that! Take back from PS? I would like to emphasize on elegant coding style once more. This is what differentiates student from an industry person. Read about “System Design”. Most of the companies like Linkedin, Google, Facebook, Quora, Square etc open source its design via engineering blogs. Give it a read. It’s worth your time.

The overall experience during my five months’ internship at Flipkart Internet Pvt Ltd, Bangalore was great. I was not just well trained technically but was also exposed to the high working standards of the company, the very flexible and optimized working conditions, highly qualified and experienced employees (including top level managers) with whom I had a constant interaction at daily standup meetings and could share my training issues as well as indulge in planning discussions for upcoming tools. The working hours were flexible which were around 8hrs from Monday to Friday. I was working in “NLPTech” team in the Customer Service vertical of Flipkart. My team was involved in the development of projects like social media sentiment analysis, using Machine Learning techniques to identify patterns in Big Data, developing CustomerAgent Chat for an enriched user experience, etc. My project dealt with Supervised Classification of Product Reviews given by Flipkart’s customers to identify if the review was a complaint and to create an incident for each such actionable review. The objective was to create a tool which facilitates Natural Language Processing of review data and classification of reviews into Actionable and NonActionable reviews using Machine Learning Algorithms. You are not expected to know any software beforehand and sufficient time is provided to learn the prerequisites for the project. I had weekly review meeting with my mentor and manager which were very important for the feedback and continuous improvement of my performance. All the employees were very friendly and were ever ready to help me all the possible ways. I even had access to the planning meetings of the whole team where my suggestions were always welcomed. The company also organized team outings full of teambuilding activities which added more to the experience. So I would say this is a very huge opportunity which will not just add to your resume but also help you hone your soft skills. While implementing my project, I learned Maven in Dropwizard, used Morphia client for Mongodb and learned to use a wide variety of web technologies including HTML, CSS, Javascript, JQuery, Angularjs, etc. The Machine Learning techniques I learned during the course of my project are listed below: 1. Supervised Learning Algorithms: Naive Bayes, Bernoulli’s Naive Bayes, SVM, Linear SVC (onevsall technique), Feature selection and extraction, Analysis of ML algorithms on the basis of precision, recall, accuracy metrics and tradeoff between precision and recall, Calculation of Bias, variance, regularization, Model selection, error metrics for skewed classes, Feature set selection for anomaly detection. I completed the Machine Learning course offered by Prof. Andrew Ng, Stanford University through Coursera to facilitate the process of learning ML techniques and their usecases for the project. Overall, it was a very enriching experience as it helped me widen my knowledge base and awareness of the working of ecommerce business.

My PS-II station is Flipkart, Bangalore. I have been working here as a part of Seller-Platform team. Past five months have been an amazing Learning opportunity for me. I was introduced to various programming

186 concepts and was provided with a platform to implement those concepts. Major chunk of my project involved development In the Java Language. For the implementation of the project, I had to Learn various concepts like dependency Injection, setting up config, auditing, UI development. middleware concepts, Restful services, Object relational mapping, etc. Apart from learning various software related concepts, I have also realized how working in industry is different from academic projects. In industry there is a lot of emphasis on correcting the corner cases associated with a given program. Also, the programs are subjected to large number of stress tests so as to make them as bug-proof and future-proof as possible. The programs are also reviewed by various people to reduce possibility of bugs. Moreover, even while writing a program, a lot of emphasis is laid on making it easy to read, understand and manage. These kinds of programming practices are very typical to industry. Practice School experience has also helped us become familiar with the essential attitude and the working environment of companies. We also got an opportunity to interact with and learn from many people who already have a lot of experience of working in industry. The constructive feedback from them has helped us in developing new skills as well as refining other skills. Hence Practice school has provided us ample opportunity to implement the techniques learnt in classroom as well as learn new concepts. I sincerely believe that due to this hands-on experience we are now better prepared for the future and experienced gained here will help in smoother-transition from academics and I am really grateful for this opportunity.
