Hardware Interviews
Aren't LeetCode

Practice real RTL design interview questions.

Write SystemVerilog in real time and get instant, simulation-backed feedback.

module dut (
  input  logic clk,
  input  logic rst_n,
  input  logic valid,
  output logic ready
);
always_ff @(posedge clk) begin
  if (!rst_n)
    ready <= 1'b0;
  else
    ready <= valid;
end
endmodule

Most platforms prepare you for the wrong interviews

Software-Centric Questions

Algorithms and data structures don't translate to RTL design thinking.

No HDL Support

Existing leading platforms don't support RTL questions intended for SystemVerilog or other HDLs.

Mismatch With Reality

FSMs, pipelines, and testbenches are what actually matter in hardware design.

Why ZeroSlack

ZeroSlack is built around how hardware interviews actually work.

RTL Problems

Questions from real design and verification interviews.

Live SystemVerilog

Write synthesizable RTL in real time.

Simulation Feedback

Immediate correctness and behavior validation.

Built for FPGA, ASIC, and DV candidates

Whether you’re preparing for internships, new grad roles, or senior hardware interviews,
ZeroSlack helps you practice the skills that actually matter.
