I had a bad experience with this brand name.

First of all, I applied for backend openings through LinkedIn which suited my interests, but I never got a call (even with a referral from a friend).

Suddenly, a recruiter from an agency called me out of the blue, saying they had an opening with Walmart, but in Android app development.

I told them I was interested in server-side work, not app-side. They said this role had both. However, during the interview, the interviewer asked me a few basic Android app questions, which I answered.

I also answered data structure-related questions. But I reiterated that I was not interested in working on the app side. Why waste everyone's time?

• I don't think the screening process is fair. I've seen agencies tied up with HR in previous companies.
• After the interview, I asked for feedback, but received no email.

Luckily, I have offers from two other product-based companies, so I don't care much.

But it was definitely an unpleasant experience.

Do you know Kotlin?
