Weaknesses?
Well, I probably have some of the weaknesses of academic people: I am very passionate about what I do, and sometimes I tend to get lost into details: trying to push too hard either in cleaning or modeling my data to get just a little bit of gaining in knowledge. While this is appreciated in academia even right now, I try to make weekly and monthly goals and try to stick to it. Also this I was shaped in by academia, and I am sure in the industry I will quickly learn to be fast-paced and careful about the final product we have to deliver.
Question to ask them?
Classical
What brought you to this company?
What has been the most challenging?
How many DS you have? What is the interaction?
How does project planning and scheduling happen?
Do you have Hackathon/learning workshop? etc
How hard it is to understand the wake word?
What are the main challenges in working with a cloud based system?
How do you deal with accuracy vs speed? I guess your madel has to be fast do you have to make compromises?
How often do you update the alexa core?
What are the main inventions or simple tricks you used for NLP? undertansding what skills to use? I heard in a conference you change the schema?
How do you do context carryover like To handle more-natural spoken interactions, Alexa must track references through several rounds of conversation. If, for instance, a customer says, “How far is it to Redmond?” and after the answer follows up by saying, “Find good Indian restaurants there”, Alexa should be able to infer that “there” refers to Redmond.? in simple word.
Can you avoid the wake up word Alexa for consequent request
Can you squeeze alexa for offline users? that seems to be cool for somthien like cars? at least some of the core functionality.
Do you ever make some of your data avaialable for public researcher or challenges etc?
Is it hard to understand when a user finishes a sentence? how do you find the optimal end point not too early not too late
Hobbies
-Arduino and repairing building computer. Show manual I loved outreach but hard in France. (Communicate gives meaning to what you do allows you to understand better and sometimes you can see a quick impact on people lives.) - baking more than cooking I have always loved to learn more about IOS but I just scratched the surface. The usual/ staying in nature.
Salary questions?
“I’m more interested in finding a position that’s a good fit for my skills and interests. My salary range is flexible and I’m confident that you’re offering a salary that’s competitive in the current market.” Does this answer?, I am very open to discussing specific numbers if you want. “Well, according to my research and past experience, my understanding is that 55-70K per year is typical for PhD based on the role, requirements and my profile.”
How would your friends describe you
My best friend since preschool, that played professional football with me, would say that I’m a charismatic leader detailed-oriented team player since I was the captain of the team. He does not know that while I like guiding and helping people I am quite shy and introvert and I recharge by walling in nature. My current friends would probably say that I look very shy but then I am always the one that decide which restaurant to pick!My friend in college would probably say that I’m extremely persistent – I’ve never been afraid to keep going back until I get what I want. When in my master I really wanted to do my Phd in a bif ivy league US universities but it was not simple from a small city in Italy. I prepared for months did not take no for an answer and finally got into my dream school.
Why are you leaving your current role?
I’ve learned a lot from my current role, solid math and statistics skills, critical thinking, ask hard questions and think big but now I’m looking for a new challenge. I want a dynamic more collaborative and fast paced enviroment where the skills I will lean and apply have a quick impact on the product the busness or custumer life and satisfaction.
Why should I hire you?
You should hire me because I’m the best person for the job. I have years of experience among the brightest minfs in the world where I learn how to collaborate, learn, lead and communicate. I have very strong math tats skills and years of data analysis and interpretation but more than I can ask the right questions and work hard to deliver a product that can answer them.
Ask them questions?
Can you do transfer learning with speech recognition model and RNN?
what is the challenging of detecting the end of a sentence?
or hearing Alexa to start?
What is the main challenging of working with a cloud model?
apart from storage balance between time and accuracy?
How is the principle of learn an be curious implemented? do you have seminars etc?
I am not very familiar with . But it seems like a very cool idea/solution/technology. Can you tell me more about it?
How to answer ownership questions?
Ignore boundaries between jobs and departments if necessary to get your project done. If you see a problem and it’s not in your department, you will try to fix it. Along the same lines, you will manage every dependency and won’t make excuses if something goes wrong. You won’t say, “That wasn’t my job to take care of.” Think about the impact of your decisions on other teams, sites and the customer over time. Consider future outcomes (scalable, long-term value, etc.) Coach and mentor your team to understand the big picture, how their role supports the overall objectives of Amazon, and how it ties to others.
What is your favorite algorithm?
it’s a joke sorting algorithm because it is largely impractical. However, the solution is so intuitive that it begs to ask why no one ever thought about it before!
For the lesser mortals,
It basically involves spawning a new process for each element (n) in the array, sleep for n seconds and then print the number n. In the end, the numbers will be printed in the order of their size, thus sorting the array eventually.
For element(n) in array
Spawn a new process
Sleep for n seconds
print n
Exit process
End For
More seriously work on djikstra or simpler one binary search. (make the point that it is useful and intuitive.) (use a unfair coin to do fair coins extraction)
- Provide an example of when you personally demonstrated ownership.
Tell me about a time you went above and beyond.
Tell me about a time when you took on something significant outside your area of responsibility. Why was it important? What was the outcome?
