4 | What's your stak? | 기술셋 | My stack is Java, such as Spring, Play framework, Android and for storage, I use Oracle, Mysql, Nosql like redis. I like to use Node.js, Angular.js and JQuery. | |||||||||||||||||||||||||
5 | Strengths/Weaknesses | What are your strength? | 강점 | I have various experiences and assets involed in IT projects. and also I have latest hands-on skills. Especially, I've played the role of a software development leader, so I usually lead several architecs, such as dbas, technical architects and software architects. This is my strong point. | A quality in me that I really appreciate is that I am very hungry, and I hustle to deliver results. I may not be the best communicator since English is not my native language, but I am very fast and efficient in implementing things, and that really defines the type of technologist that I am. Less of a talker, more of a doer. | If we contact your references, what strong qualities would each one of them tell about you, also what areas would they say you need improvement. What are some adjectives your coworkers would use to describe you? Why should we hire you? Why should we not hire you? | ||||||||||||||||||||||
6 | What are your weakness? How do you handle challenges? Tell me something that’s a challenge for you.

I just studied over 20 classes including SEO and web security in previous companies like LG-CNS. and I shoud study by myself and with study group in order to catch up with co-workers. Within short period, I could lead many developers with project common modules and standards in the project. | As you can tell, English is not my native language. When I first joined Locket, I couldn't speak much of English. However, the team really liked me because I got things done quickly, and that's what Locket needed as an early stage startup. While I put a lot of effort to improve my English, my hustlng and getting things done has defined the kind of technologist that I am. | ||||||||||||||||||||||||
7 | Tell me about the project you are most proud of | 자랑거리 | We are small group, but we have tried to do lots of things to add new values to our user's lockscreen. In order to make high-quality pictures, we worked with designers manually and made our own CMS. and in order to analyse user's needs, we used serveral mobile analytics tools, such as Mixpanel, Amplitude or we analysed it with big data tools by ourselves. | One thing that I am proud of my work at Locket is that because it's a very small team, I wear many different hats and stay nimble to do whatever the company needs. For instance, the company needed the content management system in order to close a deal with a publisher last minute. So I built it without a real designer or a real mock up. | ||||||||||||||||||||||||
8 | Do you have a special talent that you would like to share? Why should we hire YOU? | I usually handle back-end and front-end including system configuration. I mainly use java and javascript, such as Spring, Play!, angular.js. but I can use android, python, groovy, shell programming. And I'm good at estimate any layer skills and adopt them quickly. | Same as "what are your strengths" question | |||||||||||||||||||||||||
9 | Accomplishments / Failures | Which one of your accomplishments are you most proud of and why? | I supported for various and changing requirement of business team promptly. I made servers and made server apis and front applications, moreover I built deployment automation environment and analysed log data. | At my previous company in Korea, due to my seniority, they were pushing me to become a manager. However, I love building things and I really wanted to code. So I managed to get an intro to the Locket team who I thought was doing some really cool stuff, and landed a job as an engineer where I spent most of my time coding. I brought the rest of my family from Korea and they are now adapting to this new environment. I am so proud and lucky to have this kind of opportunity. | ||||||||||||||||||||||||
10 | Passion / Hunger / Motivation / Goal | What's your short term or long term plan? | 단기계획 | I want to be a software architect who can analyze and design the s/w architecture and provide common modules for the whole developers in the field, leading enterprise scale project as long as I can.

12 | Walk me through the steps you took to reach an important long-term goal. | I have always loved to make the application which people want to use. for that I have to have the way to identify the user's needs and catch up with new trend. In order to do that, I want to get the big data skill and adopt to the company's project or my personal project. | ||||||||||||||||||||||||||
13 | What are your career goals? | 장기계획 | I have always loved to make the application which people want to use. Doing it as long as possible is my goal. | I want to be a top notch individual contributor in the field of big data skill and visualization programming. | ||||||||||||||||||||||||
14 | What motivates you? What excites you? What do you like about what you do? | 동기부여 | I usually like to adapt new trials to the project, whatever it is technical things or management methods. so that I keep studying about various things involved in software architecture and methodlogy. In that sense, I am an autonomous and self-motivated person, and my most important factor of motivation is achieving recognition as a key person. | I love learning and trying new things. | ||||||||||||||||||||||||
15 | Describe your perfect job. | 완벽한 직장 | Following the trend, I want to adopt the appropriate new skill to the project as a team members continuously. | I want to be a top notch individual contributor in the field of big data skill and visualization programming. | ||||||||||||||||||||||||
16 | What do you do in your free time? | 여가시간 | I like to make my personal application including my own server. | I love learning and trying new things. In fact, I wanted to suggest that Locket makes its own web app, so I built it over my commute in Bart. | ||||||||||||||||||||||||

18 | Leadership | What's your opinion about good leader and good member? | 좋은 리더, 좋은 직원 | In my opinion, there are 3 kinds of good leader in my field. The first type is a manager style leader, the second is a business oriented leader, and the last one is a technical leader. Many people become the first type or second type leaders without concerns of technical leading, even though they had worked on the technical base for a long period. I believe that I can lead my members fully as a technical leader. And I believe that if we can help the members with just one of 3 kinds of leading abilities professionally, we can be a good leader. => On the other hand, I have one thing to emphasize about the characteristics of good members. That’s cooperation with co-workers. Of course, personal competence is most important in the company, but even though with great competence and poor cooperation, the team can succeed one time but the team’ atmosphere will collapse, so the success can not be going on. | As a member, what I like about Vivek is that he hears everyone out and then is able to divide up the roles and responsibilies so we can divide and conquer. A good member is somene that can really support the leader in achieving his/her goals and help other coworkers achieve the same. | |||||||||||||||||||||||

So I had experiences to give some advices to my juniors personally and take care of their job careers, and so on. | NA | |||||||||||||||||||||||||
21 | Is there any experience with other team members? | 팀원간의 관계 | - architect : I think normally architects have much pride, so I need to show respect to them. Then they’ll do the best as much as they can do everything. The only thing we need to do is preventing the bad way to go. - QA : I usually got the audit about technical documents from QA. in the big scale projects, we usually got the internal audit or external one. then in the most of case we got document inspections about technical issues. - tester : As for me, mostly co-work with testers, was n’t getting testing, I usually provided the information about common modules and technical traits to them, such as UX, performance guideline something like that. - developer : As a development leader, I guided the development standard and solved the technical issues. and sometimes I provided automation tools for development productivity and standardization of developers. - BA : I worked with business analysts for defining the requirement of UX and reusable common components, and in korea, normally business analysts become business designers, so I supplied the information of standard development process and guide for cooperation with developers, such as specification documents or communication tools. | Of course. On daily basis, I work with all four of my team members. It's very important that we get along. I spend more time with my team members than my wife. | ||||||||||||||||||||||||

In that project, we should make over 100 countries' localized web sites co-working with american design company, publisis modem in new york. We had several technical issues such as localization, network latency, it governance etc. Before that project, LG Electronics had 4 seperate service center in the world. but it was really tough to update the site and solve the system failure. So with the project, LG Electronics wanted to change from distributed multi-instance service to single-instance service. It means making center in korean and service globally. In order to solve the problem related with localization, we used CMS (content management system), HP Autonomy's teamsite. and search engine Oracle endeca. and for network latency, we worked with CDN solution, CD networks in korea.

After that, it'll be helpful to verify the result with serveral ways. | ||||||||||||||||||||||||||
29 | You do not know anything about the technology you need to work on, you got a bug to solve, how would you start | At first, I'll check out the sympthom. and analise the log.

30 | How do you go about learning new technical skills? | I'll read about the basic concept and funtional characteristics about the skill.

36 | Random Questions | What do you think is the next big thing in technology? For example, search engine is Google, social media is Facebook, etc. etc. | What I have a interest in is intelligent personal assistant, like google now.
