    Prior to now, I wrote about how recent AI developments are changing data science interview loops from a hiring supervisor’s perspective. 

    I went by means of a number of interviews myself. Job looking is at all times worrying. Being on the opposite aspect, I noticed how a lot ChatGPT may streamline and speed up the interview preparation course of for knowledge scientists. 

    Subsequently, on this article, I’ll share my ChatGPT hacks for job search and interviews with actual examples. 


    Step 0 — Create a ChatGPT Undertaking

    Earlier than getting began, I extremely advocate creating a brand new project in ChatGPT to arrange all of the recordsdata and conversations. Job search is rarely a simple and fast course of — you’ll seemingly have separate chats for various positions. A ChatGPT mission retains every thing in a single unbiased folder and ensures persistent recollections throughout all chats. 

    For my setup, I uploaded my resume and previous tasks in order that ChatGPT can higher perceive my background and make tailor-made suggestions.

    My previous tasks doc is a set of my finest tasks that can be utilized in my resume and interviews, written within the R-STAR construction. Right here is one instance:

    R(esult): Construct an AI-based inner app that centralizes buyer suggestions with automated suggestions classification and evaluation. That is now a essential software for PMs and Engineers to set the product improvement roadmap.

    S(ituation): Now we have buyer suggestions scattered in 20+ totally different knowledge sources (NPS, CSAT, different surveys, CX Circumstances, In-product suggestions software, Buyer Calls, and so on.). The maintain numerous values however are usually not being shared and analyzed broadly and successfully.

    T(ask): Consolidate all the information sources and shut the suggestions loop between Buyer Help and Product groups.

    A(ction): 1. Constructed knowledge pipeline to combine all these 20+ knowledge sources into one supply of reality dataset. 2. To uncover the topcs and tendencies, we tried conventional NLP fashions (BERT), however they took a very long time and the output wasn’t fairly steady. Then we switched to OpenAI API for classification and summarization — after a number of rounds of immediate engineering, we achieved excessive accuracy inside every week (70% label accuracy out of 11 classes). 3. Developed an automated pipeline to course of the brand new suggestions with OpenAI API every day and collaborated with eng to arrange an inner server and app to make the software simply accessible to everybody.

    R(esult): One cease store for all buyer suggestions, facilitated roadmap prioritization. Gained Hackathon ‘Buyer Love’ award and All Arms cultural level shout out.

    As soon as the paperwork have been uploaded, I added a project-level instruction so ChatGPT may act as my customized profession coach. Right here is my immediate:

    I’m making use of for Knowledge Scientist roles in the US.
    You might be an skilled profession coach specializing in knowledge science job search and interview preparation.

    Analyze my resume, portfolio, and previous tasks to totally perceive my background, abilities, and experience.

    Your tasks embody:
     1. Job Search Help: Analyze job descriptions and establish ability or expertise gaps.
     2. Resume & Portfolio Refinement: Counsel focused enhancements and assist tailor them to particular roles.
     3. Interview Preparation: Create structured research and preparation plans for each technical and behavioral interviews.
     4. Mock Interviews: Conduct lifelike mock interviews with suggestions and scoring.

    Please preserve knowledgeable tone and at all times present sensible, detailed, and actionable steerage.

    Step 1 — Software  

    Analyze Job Descriptions and Customise Resume

    The job market right now could be very aggressive. Subsequently, it’s important to fastidiously learn the job description and customise your resume accordingly. ChatGPT makes this course of a lot sooner. 

    Within the sections under, I’ll use the Data Scientist, Platform and B2B Products place at OpenAI for instance. Disclaimer — I didn’t actually apply for this place, however really feel it could possibly be enjoyable to make use of an OpenAI opening to raised illustrate the concepts on this article 🙂

    Step one I took was to share the job description with ChatGPT and ask it to assist me perceive this position higher, together with its area, knowledge science use circumstances, and key abilities. In case you are undecided if a task is an efficient match on your background, you may as well ask ChatGPT to judge for you. For instance, under I requested it to match two totally different openings at OpenAI and make a advice.

    After getting a very good understanding of the place and have made up your thoughts to use, ChatGPT can shortly replace your resume primarily based on the area and required abilities. Within the screenshot under, it generated a custom-made model of my resume and highlighted probably the most related experiences. You can even add extra particular directions on what and the way you need it to vary, and maintain iterating with ChatGPT.

    One factor to notice, although — I did spot some apparent errors, such because the reversed title sequence beneath my employer’s title. Be sure to don’t simply copy and paste every thing it writes, however learn by means of your new resume line by line and proper any flawed or hallucinated contents 🙂

    Within the job utility course of, you may as well use ChatGPT to replace your LinkedIn profile, edit cowl letters, and draft referral request messages.

    Step 2 — Interview Preparation

    Now, let’s assume your functions received some traction with the assistance of ChatGPT. Congratulations! Time to prepare on your interviews. 

    1. Perceive the Enterprise Context

    I don’t often go straight to mock interviews. As a substitute, for each place I interviewed for, my first step of interview preparation was at all times to analysis the merchandise and enterprise fashions, take into consideration key metrics, and provide you with knowledge science use circumstances. ChatGPT will be the right brainstorming accomplice right here. Let’s see an instance under:

    Firm analysis with ChatGPT (picture by the creator)

    On this case, ChatGPT generated a reasonably complete and detailed desk by itself, summarising lifecycle levels, product focus, key metrics, and knowledge science use circumstances. That being stated, I really feel it’s extra useful to take a stab your self first. For instance, after I was getting ready for my DoorDash interviews (my present employer), I drew a thoughts map and requested ChatGPT to refine it additional. This hybrid method helped me to reinforce my understanding and spot gaps.

    2. Product Case Interview Preparation

    Product case interviews have been more and more vital for Knowledge Science roles, particularly given AI’s sturdy functionality in coding. Consequently, I often spend a minimum of 50% of my interview preparation time right here. ChatGPT will help you discover and create role-specific pattern circumstances and conduct mock interviews with you. 

    Within the screenshot under, I merely described the widespread subjects within the product case spherical with query examples. The generated case interview questions adopted the sample fairly properly, whereas tailoring to the enterprise context of this Platform and B2B Merchandise DS position.

    With these beneficial query prompts, subsequent, you possibly can conduct mock interviews with ChatGPT. A mock interview generally is a very costly service. For instance, DataInterview costs $247 for a one-hour mock interview, and an InterviewQuery premium subscription, which incorporates mock interview service, prices $79 per thirty days. After all, training with actual individuals has its advantages, however ChatGPT is free (assuming you might be already a subscriber) and customizes to your background!

    I like training in real-time with the voice mode to simulate an actual interview setting — I requested ChatGPT to behave because the interviewer, evaluating my responses and asking follow-up questions. Beneath is a screenshot of my mock interview after I was getting ready for DoorDash’s onsite.

    3. Behavioral Interview Preparation

    ChatGPT is equally highly effective for behavioral rounds. Apart from conducting mock interviews, it might probably match your previous tasks to widespread behavioral query subjects, akin to dealing with conflicts, management, cross-functional collaboration, and prioritization, and refine the storyline for concise and compelling interview responses.

    4. Create Interview Preparation Plan

    ChatGPT is named a very good planning assistant. Seeing every thing it might probably do above, you possibly can present your timeline and focus areas to get a concrete interview preparation plan and a every day guidelines.

    Step 3 — After Interviews: Provide Analysis and Negotiation

    The final stage of the job search course of is the provide analysis and negotiation. I do know you might be very excited to obtain the provide, however don’t simply settle for it as-is. In accordance with a study, 73% of U.S. employers say they’re open to negotiating wage on preliminary presents, however 55% of candidates don’t ask for extra. As an information skilled, I’m positive you perceive the ability of compounding — even a average enhance compounds over time by means of raises, bonuses, and fairness. 

    ChatGPT will help you analysis related presents within the trade, examine compensation packages, draft recruiter replies, and put together negotiation scripts. 


    Ultimate Ideas

    The job search course of can really feel overwhelming, however instruments like ChatGPT flip it right into a extra structured journey. For me, ChatGPT acted as my private profession coach, serving to me keep organized, environment friendly, and assured.
