Interview Tips & Stories

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.

Interview Preparation Tips

Professional and academic backgroundI applied for the job as Data Analyst in BangaloreEligibility criteriaNo CriteriaJumbotail interview preparation:Topics to prepare for the interview - SQL - Basics and Advanced, Guesstimates, Puzzles, Problem Solving, Case Studies, Basic statistics knowledge, Company related informationsTime required to prepare for the interview - 1.5 monthsInterview preparation tips for other job seekers

Tip 1 : Extensively practice on SQL, SQL queries, extracting data, different types of joins as I had to solve and extract specified data from a dataset in front of the interviewer during the interview. Also, there is a telephonic pre-interview round that is focussed on SQL and Statistics basics. You need to clear that to move to the interviews.
Tip 2 : Practice lots of guesstimates, puzzles, problem solving and Case studies. Guesstimates may include questions like estimating the total area under warehouses in a specific region (I was asked something similar to this). 
Tip 3 : Extensively read about the company, JD and the core values of the company. They seem to focus extensively on these values and you need to prove that you fit within them.
Tip 4 : Be really cool, confident and you need to know even the tiniest details of your project work. Grinding on projects and tech skills are a part of all interview rounds.

Application resume tips for other job seekers

Tip 1 : Clean and Concise, only put things that you are very much comfortable in answering even to the tiniest details.
Tip 2 : Heavy focus on technical Skills. Mention the exact tech skills and project work/tech you used on those projects because they really pay attention to every nook and corner of your resume. Include you extra-curriculars as this is extremely important during the interview process. They will ask you to mention/describe situations where you showcased a particular skill (for hints related to these, refer to the core values section of their website.)

Interview Preparation Tips

Interview preparation tips for other job seekers - This interview was for Data analyst role at Reliance Retail. First , I had online aptitude test-50 questions 12 minutes. You need to at least solve 20 correctly. Post this I had online technical interview which lasted for about 40minutes. Initially the interviewer asked me about few accomplishments from my previous employment which had impacted business. I took him through few major projects that I worked and how these impacted business. I made sure to keep everything aligned to data analyst role. I spoke about what Data visualization tools (Domo/tableau) and languages(SQL) I had used previously to analyze data. He had follow up questions and I again made sure to explain clearly by highlighting my role. Next , there was one scenario based question asked.
Q: There are a couple of reliance stores that are bleeding(doing really bad) in one region. You have all the necessary data related to these stores. What would be those factors that you will consider first ? What will you do to ensure these stores do well.
Since I had retail background it was easier for me to understand the scenario based question. The interviewer wanted to understand how I would approach the problem.
Last, I had few questions to the interviewer based on the role.
On the same day I received call from HR saying that I have cleared the interview and offered the role.
